just got back last week from park city/canyons. Heres the 411. Conditions were lacking if you are looking to just jump of a trail anywhere and hit everything back country style. The maintained trails are solid and my best day was at park city. BUTTT i reallly recommend Snowbird because they just got 15 inches last week and snowbird was absolutely epic. All 3 places are great but IMO snowbird is not to be missed. Take the hour shuttle or drive if you rent a vehicle and do it. You wont regret it, but you need to be an advanced rider to be able to ride this mountain.. If you also get some snow, Jupiter Bowl in park city is awesome.. the glades over there kick ass.
