This park is nice and big and right at the beginning of the gay village. Its a really good spot in the summer to hang out and people watch.
During pride, it turns into part central with huge dances and shows, which are usually free (or $2 donation).
Theres lots of homeless people around and people selling/doing drugs - but this is right downtown and theres a couple homeless shelters around. They usually just ask for money and if you say no then thats it. I've been going to this park since I was 14, and I've never had trouble. Theres also lots of cops around this park, so it should be all good.
