I skied it last Tuesday on my own. There is a path you can follow that will take you out to German Flats Rd. where a bus will pick you up. This is the bus that drives back and forth between Bush's two mountains. There is no charge for the bus. Unless you have no experience skiing trees and/or have no sense of direction, the $70 is a ripoff.
Sugarbush is in desperate need for new snow. They did not get much snow from the New Year's storm. Unless Bush gets decent snowfall by the time you go or you don't mind skiing rocks, stick to the snowmaking trails.
Killington has much more snow than Bush. If you want challenging terrain, go to Magic, which also has better snow than Bush right now.
