Every park in a large urban city is a gaint bathrooms for dogs and hobos. I once tried to sit by a tree in a park and a hobo came over and started pissing on the other side of said tree. It was a big enough tree that he couldn't see me on the other side. I don't sit under park trees or lay on the grass anymore. Tbh I don't live in a big city anymore. This happened in Toronto and then I moved to San Francisco. San Francisco is one giant hobo toilet. I've never seen so much human shit on sidewalks before.
