Try to ski at other resorts. Two days at Northstar is enough for me, anymore and it gets old really fast. Make sure when you ski Northstar it is on a weekday, or before the bay area is out for Christmas. Try to get over to Squaw and Alpine if possible, they're half an hour from Northstar at the most. There a TONS of resorts around Tahoe, hit as many as possible, so much terrain and the best parks around. Glad to see you chose Tahoe over Utah and Colorado, those states get their dicks sucked by NS, even though I think CA has North Americas best parks and if you are here at the right time, the storms will blow you away. We get shat on. Enjoy the trip man.
