In an era of rapid consolidation, it's surprising to see such a large resort go the opposite direction. Powdr was far from perfect. They did a few large capital projects, but went many years between them. Their infrastructure is aging and needs to be overhauled or replaced. I think there's always some concern about one's home mountain changing hands, I think "the devil you know" is the saying. I know the new owners might not be "real" locals, and they're independently very wealthy, but a new owner with deep pockets might be exactly what Killington needs to fix a lot of the shortcomings that have developed in the last few years.
In my opinion, there are 3 things that need immediate attention. First, replace the Superstar lift. It's on its last legs, and having it go down for any length of time would be devastating. Second, replace the Skyeship cabins. They are in very poor condition with missing/broken parts, and many cabins were tagged out last season, leading to a loss of capacity. It seems parts are harder to come by than they used to be. Third, improve reliability of the snowmaking system. So much valuable time has been lost the last few seasons due to pipe blowouts and other issues. Fix those issues in the short term, and start implementing a plan for a full modernization, along the lines of what Sunday River and Belleayre have done. It really makes a difference, and doesn't require a large one-time investment like lifts and lodges do.
