Wow- that'll be fun. I've skiied Utah a number of times - Alta and Snowbird are two areas that I remember. If you take the tram to the top at snowbird on a sunny day, the view is unbelievable. It's like you are on top of the world. Those are some big mountains.
Deer Valley, Park City, the Canyons are the places we'll be at. Haven't been to Utah to ski and looking forward to it.
