just travel to west L.A. and find a good safe court there (maybe UCLA) has a few- not in the former Pauley pavilion. You might find a really challenging pick-up game in that area. The whole city is yours to explore. look for the best!
It is a coed group. They let everyone play, it is not too competitive though. We go to play, but as far as I can tell the players don't play to win. There are no fouls, and people aren't playing like they are getting payed to win. I have seen that at other games.
I like the place. They are called pick up game sports zone or www.pugsz.com
