For the prior three years I had a season pass to Killington. Fearing bad things from the new owners in 2007/2008 ( I was right), I decided to try Okemo. While there is no doubt that Killington is a much bigger, more diverse and much more challenging mountain, Okemo provides a far more pleasant experience. Grooming is superior, people are actually nice, the lines are usually not bad, and people in line are corteous, even the snowboarders are more tolerable. Unless you are a super expert, you will definetely enjoy Okemo, though after a few days, it will get a little boring.
