SoCal (San Diego specifically) Ownz Joo!!! I try to organize something every other month or so... then there's also the spontaneous "Hey, what are you doing for dinner? Let's go to Bamboo Hut" meets. There are many hotties at Bamboo Hut.
As for coinciding with one our track days, just keep following the West Coast Forum... I usually post Track-Day information about 1.5-2 months before the actual event, so people can plan accordingly.
