On the opposite side of it, I was at Purgatory mountain Colorado the last open day and the Governor lifted mandates on masks outside, so did the mountain. I got on a lift and a younger couple got on same chair. One mentioned to put my mask on, I was like no thanks, go take it up with your governor and the mountain management. When there is no mandate, I sure hope people don't expect people to wear masks if they choose not too. Someone can choose to wear a mask and others can choose not to. I can see where this could get out of control in the future. "Hey, it's a bad flu season, put a mask on" No thanks.
They lifted the mask mandate for lift lines and chair lifts at A-Basin two days before we left Colorado and came back to Tahoe. (April 30th??)
Masks were still enforced in common outdoor spaces with tables and such, except of course when you're eating and drinking, and masks still required inside buildings.
That being said, a group of mogul kids (maybe 10-12 years old) behind us, said (politely), "could you please put your mask up?" I kindly told him that the mandate for lift lines was lifted the day before. His eyes got big and he asked, "Really?!!"
Later when we saw the group of little mogul skiers they were all wearing masks, so I'm pretty sure the coaches were still reinforcing it. Probably some protocol for their mogul camp.
On the flip side, my face and lips haven't been exposed to the elements all winter and they took a beating for the two days we were skiing without masks. Poor lips cracking.
