i used to night ski quite a bit when they just had the little park. can't wait for a real park. good lenses warm clothes and a flask are essential, but its really not that icy, pretty bearable.
i was checking out thier map for this year and it had a new Three Kings park next to Pick and Shovel.
In the most recent Freeskier issue I've received, there is a Park City add claiming that the Three Kings park will have night skiing until 9Pm.
Ill try and post a picture. Sorry if the quality is poor
