I don’t think that would happen again unless for some reason it gets so off the rails we go into “Stay at Home” orders again. That was what brought about those closures, to literally try to pinch off any attractive reason to get in your car and drive somewhere. I think that ship has left the port though and not coming back.
But temporary closures of operations is certainly in play if there are local outbreaks or staff outbreaks, IMO.
Having uphill gear will come in handy at some point and allow for more options, as maybe now you *really* want to avoid ski areas during the holiday periods even if they are fully open. Most locals avoid that time or plan differently, but maybe now is when you take a couple extra trips to the Cold Hollows, Eden/Belvedere, Gilpin Mtn, etc.
