I live in Moorpark. Thats Ventura county.
JT is 3 hours. The Needles are 4 hrs, Stoney point is 15 min, Echo cliffs (with hike) 1 hr 15 min. Malibu Creek, (with hike) 40 min. All that great hiking in the San Gaberials from 45 min to 1.5 hrs.
Mojave is about 1-1/4 hrs. NJC is 2 3/4.
I like living on the north end of our great metropolis, and after driving home late on a Sunday nite after a weekend in Bishop, the thought of having to keep goin down to lets say Long Beach, would make me cry. If Irvine or SD, I would stop going on trips up that a ways.
