It always appeared to me this is the practice of most smaller areas in CT, Mass, and southern NH. I know for a fact it is Sundown's. A couple years ago they had the biggest whales I had ever seen, probably 14-16' high, just as wide, and just below some lifts around New Year's. Sooner places can end snowmaking the sooner they can lay people off. No point making snow in Feb or March when the mountain will be shut down in a month or so. In the years I was a passholder at Peak's and skiing Crotched, I never remember a gun going after MLK weekend. They would bury early and ride it out until the first week of April. Whereas the larger areas up north can still draw well later in the year, plus passholders would riot if the were not skiing soft bumps in April and May.
