As long as LA is part of earth, 914World is the right place to be.
If you want to meet local guys, simply post a new thread and say, "Hey LA guys/gals, lets meet up for breakfast/lunch/dinner at this resteraunt on this day at this time."
We've got quite a few members down there, so you're sure to get some people to show up. The guys down there used to do a monthly In-N-Out meetup, but I think Aaron Cox was one of the driving forces behind that and he's a married, working stiff now, so he hasn't been very active.
