Stevens pass rocks. The best night skiing in the state for sure and pow is freakin sweet. Even thought its a long drive for me (2.5hrs) the fact that you can sleep in and still have 10hrs of riding once you get there makes up for any distance qualms. Almost the whole mountain is lit up at night and the hours are from 9am till 10pm five days a week. That beats any resort I know of. Also the prices are a down-right bargin.
The only problem I have with Stevens is that they don't light up the cowboy lift or the back side at night. Other than that its pretty awesome. See ya up there.
