Tehachapi, Cal City, Rosemond

I have reason to be at Edwards AFB on Monday, and nothing pressing
over the weekend. I think I absolutely must take advantage of the
situation to fly from one of the many glider ports in the area. I've
flown (once) from Crystalair, been to Mountain Valley airport at
Tehachapi, but never Cal City or Rosemond. I would like to camp in my
truck Saturday and Sunday night, so a place to shower etc. would be a
plus. Also, another consideration is that I need 5 - 8 minutes of
help rigging on Saturday morning, and about the same de-rigging on
Sunday afternoon.
I have me, my glider, logbooks, insurance policy, and my truck. Advice
about ammenities and requirements at the various airports would be
appreciated, off line is perfectly fine with me, but sharing for
others might be good too.
Thanks,
UF
