Depends where you are in Big Bear too. You can get a different set of stations on one side from another. Last time I went up there to snowboard, I tried to pick up X 103.9, which is licensed to Lake Arrowhead and I got Recuerdos instead!
I've heard some LA stations up there, the one I remember is KCBS 93.1. But as mentioned, most San Diego stations can be picked up as well as High Desert like The Highway Stations.
