Ease of access to the Hill as well as ability to night ski.
I rate them a 5 star due to two key reasons..(1) Ease to go the hill (the fact it is freeway close) and that the roads are maintained and opened even during the heaviest of storms; and (2) there is night skiing/boarding...this allows me to hit the hill even for a few hours after a long day of work. Allows for opportunity to enjoy the limited amount of snow we receive here in SoCal.
