I went snowboarding in Tahoe 3 weeks ago, and the snow was AMAZING!
I hit Heavenly, North Star, Squaw Valley.
20 foot base, one of the best snow falls in 19 years. Lots of fresh powder.
All the casinos, or at least the big ones, are right next to Heavenly, which is one of Tahoes finest slopes. During spring break I hear they have killer parties on the mountains, and tons of cute chicks. There were plenty when I was there, that's for sure.
I've been snowboarding for 14 years and I could not recommend any place more highly than Tahoe, especially now. Utah's great, but Tahoe has a dozen resorts around the lake, from mellow, to places that hosted the Olympics. Take your pick each day....it's all there. Casinos at night, and you can show up in jeans...whatever...very casual.
And can ANY place beat the view while ripping down the side of a mountain?
