wouldn't damage the bark because the bark is an important part of the buildings as you can see. one of my favorite buildings in san francisco. the camera obscura and one of the last remaining buildings that was play land of the beach and right below the cliff house and opening in the roof that you can see there and it rotates and lens and a mirror in the opening and project what is it sees outside into a parbollic shape platform inside the building and you can see the world outside. why do i have to pay three dollars and i can go outside and look at it? it's a truly remarkable experience. first of all the preriffal stimuli is gone and

what is amazing in our area it's entire leeann loentirely analogt digital and it's wonderful and you have to check it out. this is what used to be along the beach, play land on the beach and the camera camera obscura wt of and replaced with much needed housing and this is one of the wind mills and we will get to those. this is a petting zoo, barn, nothing special and has a coupe laand there are barns all over san francisco. this little barn is in somebody's backyard, 25th street. >> there is a barn and farm

$20 million plus but it's a gorgeous building. woody can tell us about carville. >> this is the last in fact carville house. it was a community of discarded streetcars, horse pulled cars, various modes of transportation that were made obsolete by electric streetcars so cars were dumped out in the beach and sunset side and people made residences and the one is there and two cable cars and that is the upper and lower level and from the back it doesn't look like anything and they had club houses and bo hemian musicians would go out and take a dip in the obligatio ocean and romance.
