REI Liftopia You've researched which mountains have the best powder, but where can you find the best deal? Lift tickets can be expensive. Use location-based app Liftopia to find discounts on the mountains closest to you. The app also provides driving directions. Liftopia tells me you can get two tickets at Plattekill Mountain in the western Catskills for 72% off. Use the app to purchase tickets at $27 a head! Bookmark 'mountains' in the favorites section. One of these days Aspen will have a deal. The free app is compatible with iPhone, iPod touch, and iPad, but requires iOS 4.0 or later.
