Im out of martinez and saw your east bay group . admittedly im kinda new and have only been practicing for a few months. im going to my first Jam with the SFParkour people to see how i am with others, lethalbeef will be there.
Unfortunately, I'm not going to be in your neck of the woods much longer, cuz I'm moving out to Oakland at the end of the month.
I've got a sprained ankle right now which might be able to handle some parkour at the Sunday session this weekend, but I've got to see how it feels. I'd be happy to give you a ride if I do wind up going though. I'll probably know by Friday night if I'm going to go or not, and I'll let you know.
