Central and Southern California just got dumped on. Don't know if you're down for West Coast boarding, but now's the time. Big Bear, Snow Summit and Snow Valley would be my suggestions.
Snow Valley is far less crowded though - I have weekday lift tix I'm using next week that are 60% off. Totally worth it for the shorter drive and wipe open runs. Here's where I get mine: Discount lift tickets - Snow Valley - Ski For Free
and I've used the "SV5" code for years. Hope this helps
