David,
Next time you're through Tehachapi, give me a shout. If that was Labor Day weekend, you missed a chance to help me close out a fuel tank.
BTW, if you find yourself on one side of R-2515 (Edwards AFB) and want to get to the other (say, Barstow to Tehachapi) on a weekend, give Joshua Approach a call on 124.55 and ask if they're allowing transits of the area. If they are they'll give you a minimum altitude (6-7K ft) and send you on your way.
