to me, this was unheard of, that mexican workers could stand up, fight, and win. not only did they beat the labor contractor, this contractor happened to be the largest labor contractor in the delano area. he also happened to be white. to me, it was like a light went off in my head. then we started hearing that there was going to be a great -- grape strike. i was 19 years old. i did not know what that was. but i could feel the electricity in the air. i could feel the sense that something big was going to happen, but i just did not know what. one day my mother and sister came running into the house and

said, " we are on strike." they said they walked out. i had been at home because i had broken my leg. i was watching "i love lucy." [laughter] that took me away from watching it. i thought it was incredible. they said there is going to be a march. i went out and there were these workers, mexicans and filipinos, marching. there had never been a march in the city of delano. that night, there was going to be a strike meeting. i went. i could not stand the excitement of something big going on. i could taste it. i could feel it. i walked into the church of our lady of guadalupe in delano. it was packed.

people were all around the walls and yelling. for somebody to have created this, cesar chavez must be like 10 feet tall. he must have a voice like james earl jones, the voice of god. this man stands up, very well- spoken. do you remember a movie star called david niven? very distinguished, well-spoken. i thought that must be cesar chavez. he was introducing siegler to of this -- he was introducing cesar chavez. then cesar chavez walks up. he is like 5'5"with a very soft

voice. it did not make sense. the more he began to speak, the more i forgot his height, what he looked like, because i focused on his message. he talked about human dignity, the rights of workers, the fact that working people have to sell their labor, but it does not mean they have to sell their souls or dignity. the more he talked, the more i understood the power we had as individuals and collectively. the next morning, i cracked open my piggy bank. oci paid three months' worth of used to join the union. [applause]

that was 47 years ago. cesar chavez was a life changer. he made you believe you were capable of doing much more than you believe you were capable of. he said that imagination in new and that belief in yourself. he fed that imagination and belief in yourself. i went to chicago. i just turned 21. he said we were going to start a boycott and they needed me to go to chicago. me. i had barely graduated from eighth grade. i had been a farm worker all of

this time, an immigrant. he said, you have to go to chicago for about two weeks. [laughter] i said, where is chicago? not far. [laughter] ok. but you have to take an airplane. i had never been on an airplane in my life. we're going to give you a name. when you get there, looked him up and figure it out. he gave me a bag of buttons to sell to raise money, one name, and $20. he put me on an airplane. who in their right mind would go to a city they have never been, you have no idea where it is, how big it is, with one name. it was not that i was dumb and young, it was that i believed.

i went to chicago. i was there for four years, not two weeks. but we did stop the sale. we did win the grape boycott. we did build the union. [applause] cesar was also a master strategist. he was a master at power jujitsu, using your opponent's strength against them. he was a firm believer in nonviolence. he also had a very strong moral core that grounded his work and police -- and belief in the righteousness of the cause, social justice, and the belief

that there is nothing you cannot accomplish when you are united and working together. those lessons are just as relevant today. today, many of the things that cesar fought for are in danger. today, we are facing difficult situations as a society. today, in the richest and most powerful country in the world, we are seeing such income inequality that we have never seen before. today, we have more millionaires and more poor people than in the middle class at any time in our history before. the unions have always been the

ticket to the middle class for working people. they are under attack like never before. look at wisconsin, ohio, indiana. look at the state of california where again the corporations are trying to take away the voice of working people. they are doing that because they believe if they are to control the wealth of the country and the ballot box that they must do away with independent political forces. the labor movement is the largest, best resource, independent political force in this country. they think they have to do away with that because it is what stands between them and complete control in this country. if you look around the country, you see all of these bills that have been introduced to limit and restrict the right to vote

for people of color, for students, for other people. you see the destruction of community organizations, acorn, it tends to defund planned parenthood. there is a coordinated attack going on in this country by the powerful in our society. it is not just that i am paranoid. if you just look at what is going on in state after state, it makes you understand that if we do not join together, we are going to see the american dream that cesar fought for, the martin luther king fought for, the out of the reach of average people in this country. we have huge challenges in front of us. the best way to honor cesar

chavez in june 19 together to make sure -- is uniting together to make sure his dream and vision for society come true. freedom is a hard-won thing. every generation has to win it again. the song was part of a movie made it was called "the inheritance." it is true. every generation has to win it again. i am glad that this event is bringing us together again. the war horses with the young, the next generation. together, we have to fight for this country, for this nation that lives on in our hearts and dreams, a nation where it is a

land of liberty and justice for all. that is our task. let's do it in memory of cesar chavez, but more importantly, let's do it for our children and grandchildren. thank you very much. [applause]

>> i have been a cable car grip for 21 years. i am a third generation. my grand farther and my dad worked over in green division for 27. i guess you could say it's blood. >> come on in. have a seat. hold on. i like it because i am standing up. i am outside without a roof over my head and i see all kinds of people. >> you catch up to people you know from the past. you know. went to school with. people that you work with at other jobs. military or something. kind of weird. it's a small word, you be.

like i said, what do people do when they come to san francisco? they ride a cable car. >> california line starts in the financial district. people are coming down knobbhill. the cable car picks people up. takes them to work. >> there still is no other device to conquer these hills better than a cable car. nobody wanted to live up here because you had to climb up here. with the invention of the cable car, these hills became accessible. he watched horses be dragged to death. cable cars were invent in san

francisco to solve the problem with it's unique, vertically challenged terrain. we are still using cars a century old >> the old cable car is the most unique thing, it's still going. it was a good design by then and is still now. if we don't do something now. it's going to be worse later. >> the cable cars are built the same as they were in the late 1800's. we use a modern machinery. we haven't changed a thing. it's just how we get there. >> it's a time consuming job. we go for the quality rather than the production. we take pride in our work and it shows in the end product.

>> the california line is mostly locals. the commuters in the morning, i see a lot of the same people. we don't have as tourists. we are coming up to street to chinatown. since 1957, we are the only city in the world that runs cable cars. these cars right here are part of national parks system.

in the early 1960's, they became the first roles monument. the way city spread changed with the invention of the cable car. >> people know in san francisco, first thing they think about is, let's go

because we have a great waste water system here in san francisco, we do about 80 million gallons of waste water here in san francisco, which means we basically fill up 120 olympic sized swimming pools each and every day here in the city. we protect public health and safety and environment because we are discharging into the bay and into the ocean. this is essentially the first treatment here at our waste water treatment facility. what we do is slow down the water so that things either settle to the bottom or float to the top. you see we have a nice selection of things floating

around there, things from bubble gum wrappers, toilet paper, whatever you dump down the toilet, whatever gets into our storm drains, that's what gets into our waste water treatment and we have to clean. >> see these chains here, this keeps scum from building up. >> on this end in the liquid end basically we're just trying to produce a good water product that doesn't negatively impact the receiving water so that we have recreation and no bad impact on fish and aquatic life. solids is what's happening. . >> by sludge, what exactly do you mean? is that the actual technical term? . >> it's a technical term and it's used in a lot of different ways, but this is organic sewage sludge.

basically what it is is, oh, maybe things that come out of your garbage disposal, things that are fecal in nature. it's sludge left in the water after the primary treatment, then we blend those two over and send them over to digestion. this building is built to replace tanks here that were so odoriferous they would curl your hair. we built this as an interim process. >> is there a coagulant introduced somewhere in the middle of this? . >> this coagulant brings solids together and lets the water run through. that gives us more time in the digestion process, more time to reduce the amount of solids. these are the biggest ones in

the world, like we always like to do in san francisco. they are 4 meter, there's none like it in the world. >> really? wow. >> three meters, usually. we got the biggest, if not the best. so here we are. look at that baby hum. river of sludge. >> one of the things is we use bacteria that's common in our own guts to create this reduction. it's like an extra digestion. one of the things we have to do to facilitate that is heat that sludge up and keep it at the temperature our body likes, 98.6 degrees. >> so what we have here is the heat exchanger for digester no. 6. these clog up with debris and we're coming in to -- next wet weather season so we always come through here, clean them out, make sure that we get maximum heat exchange during

the colder wet weather. sludge season. >> rubber glove. >> right here. >> rubber glove, excellent. all right, guys. >> thank you. >> good luck. >> this is the full on hazmat. . >> residual liquid. we're taking it time to let it drain. we don't want to get sludge on it necessarily. take your time. stand on the side of it. . >> should we let it release for a while? . >> let it release. >> is that the technical term? . >> this is the most important bolt on the whole thing. this is the locking bolt. it locks this
