I heard two rumors from speaking to staff at Stowe over the weekend. One was that they were shutting down the first weekend in April; the other was that they are holding firm to their commitment of April 24th as "we are confident that snowmaking depths can survive into late April". Take your pick. @epic?
Stowe does historically shut down in stages -- they'll shut down Spruce side one week, the gondola the following week and finally the quad.
Regardless of when final closing date is, they have plenty of snow to survive until the gathering, at least on snowmaking trails. There are still snow whales in strategic locations to patch up any holes that might appear.
As I mentioned above, I'm on injured reserve and won't make it. If after the Smuggs day on Saturday you decide to re-arrange the schedule to follow the better snow / terrain, feel free to do so.
