If El Niño hits California this year, this is the pass Californians must have: it gives you unlimited skiing at Mammoth, Bear Mountain, June Mountain, and Snow Summit. It also includes night skiing at Snow Summit, and five half-priced Bring-A-Friend tickets. Upgrade to the Premium Pass for an extra $100 and you'll get access to all Mountain Collective resorts, too. Worth the gamble? We think so.
