the pioneer log cabin and used for pevmen ps for the rec department in golden gate park and was recently restored and renovated. apparently they brought the logs in out of the woods -- out of the forest by helicopter so they 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
