Victorville is about 100 miles north of Temecula on I-15, although the cabin in Wrightwood is closer. If you remember March AFB, between Perris and Riverside, that's about 20-25 miles or so up the road.
And I stay right out by Mather when I visit friends or go to pistol matches in Sac.
You didn't say how long ago you were here, but it has definitely changed. I've been here in town for 15 years, seen the population grow from 360 in town proper to over 40,000 within city limits. It is just about like being in the big city nowadays, one big city from San Diego to LA.
