I'll look for you guys. I'll be out there with three guys launching out of Cal City. Crawdaddy, PM me the radio channel you guys are going to be using and I'll listen up for an opprotunity to join you guys for a while if the timing works out.
I don't think it's a factor for your ride, but the Rainbow Basin loop is a one way dirt road that runs counter clockwise off the main dirt road, so if you approach it from west to east, you'll have to do a couple of miles of back tracking - not a big deal.
Ride safe and have fun.
