Utah powder is amazing, and I second going to solitude on a good snow day, cause no one is ever there, it's awesome! Everyone and their mom goes to snowbird on a big snow day, so unless you get their in the first hour you'll be surprised at how much is already tracked out. Don't forget the southerly storms though, sometimes they'll roll in and basically just hover over Sundance and park city. I use to teach snowboarding at Sundance and it's not to be overlooked on a powder day with a southerly storm
Don't just live life on the edge, jump off it!
