This a fun DIY park that has been going for years in San Francisco. It's hidden so you're going to have to want it to get it and it's not for the street plaza types. Tight trannies and hard to get to zones.
To get to the spot head out of the city west on the 101 and veer onto the 280 south and take the first exit Alemany. Stay right and go into the big parking lot and go all the way to the back of the market. On the corner of Peralta and Tompkins Ave the'll be a wood fence. It's behind there. Have fun and good luck.
