Wow that sounds like a GREAT adventure. I'd make the rounds to the Pomona NHRA Museum, Petersen Hot Rod museum on Wilshire, in LA hit a couple of Cars-and-Coffee cruise-ins, hit the beach, dive into In-n-Out for burgers (ask for some "double pass fries" - yum), go to Irwindale for some local test-n-tune color.
Making passes at the CHRR is just the cherry on top. Lots to do in SoCal.
As a Midwesterner I always had a somewhat jaundiced view of the West coast racers and their accomplishments with their hot rods. But having been there I can now say they are the real deal. Not that anyone out there cares what I think LOL.
