Title says it all.
I was at Sunday River Maine and Black Mtn Maine this weekend. Black was empty, probably the cold, but never crowed anyways. Sunday River was not crowded at all, which surprised me. I stayed away from South Ridge, their beginner area. The parking lots were not even full, kind of surprising. The weekend before SR was much more crowded. Again, in this Covid year, I have only seen less crowds than usual, the one benefit of quarantining.
