saw this link on another site, Killington's GM talking about early and late season. He gave Stowe a shout-out too!
Yes, the extended season is here to stay. It’s part of our culture. Long ago we stopped trying to figure out if it’s justified, so there’s not much calculation that goes into it. At the end of the day, we know we’re not making money off opening early and closing late, but it is closely tied to our brand. It’s important for us to show that we will provide skiing and riding to our guests anytime we can. It’s a nice differentiator for us.
