I am not so sure if it will happen. The last ski area to open was Magic about 15 years ago and even that was a previously owned mountain. So my question is, will we see a new skier area? If so, where and why? Make your case....
My case is for Bigelow in Maine. It has more prominence and elevation than Saddleback and just behind Sugarloaf in both categories. It's in the same range as both of these mountains and just as accessible. When Maine was submitting proposals for the Olympics in the late 70s, Bigelow was considered for many events.
Dorset Peak in Vermont would also be another good option. Great location and good size.
