Big Bear Airport
Big Bear has a little general aviation airport. When I was in college and had time to maintain my pilot license I flew in there a couple of times. It is a nice way of cutting your commute from Santa Monica down to about 1 hour and you avoid all the traffic!
If you are going east on the 10 FWY, avoid going up to the mountains via the first exit that says Mountain Resorts. The road gets heavily congested in the winter. It is better to come up the back road on HWY 38, farther east. Another good alternative is to come up from Victorville, hardly ever any traffic from that direction.
