Snow Summit is my home mountain - have a season pass there. It does take 3 hours from San Diego. The Parking lot fills up fast. They open at 8:00 and we used to get there at 7:00 to get a spot in the parking lot and then eat breakfast and get gear on and hit the first tracks at 8:00 if you drive. There is an intermountain shuttle that takes you over to Bear Mountain with the shuttles running every 1/2 hour. If the parking lot is full you have to park down the road and take a shuttle when can waste boarding time. They have VIP parking for $20 but that fills up also.
We go every weekend and will be there the 10th and 11th. If you see the old couple on snowboards - that's us!
fyi - Summit Run is a get warm up run, but it gets really REALLY crowded by about 10:00 so you then can switch over to the left side of the mountain where the blues and blacks are.
Last two weeks has been ICY - but they just got a foot of snow Monday so who knows....
I learned to snowboard at 50! woo hoo!
