I've been to Tahoe many times, and have been to more than 1/2 the mtns there multiple times. I really love Squaw & Northstar at their respective ends of the lake. I hear Kirkwood is amazing for snowboarding, so that is the one I have yet to get to just because it's so far South and away from everything else on its own.
