Sadly, anywhere in the Antelope Valley sucks. It's the High Desert and that means 100+ F. everyday from March though October, then the rest of the year it's freezing and windy as hell...plus it's redneck and tweakerville. Your only hope is Wrightwood, but it will be a bit of a commute...worth it though, considering the other choices. Anywhere else nice, is going to be at least an hour drive from Edwards.
Nearby climbing includes Devils Punchbowl, ACH Tunnel Crag, Spring Crag, little further away is New Jack City, Big Bear areas, and Joshua Tree is less than 2 hrs away...Red Rocks under 4hrs!http://wrightwoodcalifornia.com/
