Hi Joe, I know there are active members in Salinas and Santa Cruz. Maybe get in contact with them to organize a jam in your area. Check out the South Bay communities here and here to see what's happening closer to you. Good luck and keep training!
Also, you may find this group interesting: the idea is for you to invite friends or possible people interested in parkour here, and use the tools and info available to build a safe, healthy community locally... Good luck!
