While in SO-CAL,
Head up to: 2 1/2 -3 hrs. Big Bear Lake either to Bear Mtn or Snow Summit, it has night skiing also ! With good grooming, so does Snow Valley in Lake Arrowhead along with 92 in. of snow!
Another place w/out the long windy Mtn. roads to consider is 2-2 1/2 hrs.Mtn. High off Interstate 15 on the way to Vegas, it's in back of Mt. Baldy which has the best terrain down there, but mostly off piste and ungroomed.
If you have time? Mammoth Mtn. would be worth the 5 1/2-6 hr. drive for sure they groom up the wazu with big open runs!! and over 3 000 Vert.
Good luck and have fun, most of the boarders down there spend 95% of there time in the parks not on the slopes, but watch out for the skiers that ski like they drive down there, unpredictable?
