So what's in between the inland empire, LA, and OC? Surely you guys all know of places that are conducive to just hanging out and getting together.
I think that a weekend drive would be lots of fun. Mullholland Drive, PCH, Carbon Canyon, Palms to Pines - these are all possible routes.
I still really think that a group "wrenching" day would be a blast, but we'd have to find an open campground (though that may be risky - I doubt a campground would let anybody work on cars there) or someone has to have a big plot of land where people can just drive their cars to and work at.
Keep the ideas flowing, guys.
I'm happy at the response so far!
