My home mountain is Bridger Bowl in Montana. Bridger is not sure exactly what the operating plan will be for the season at this point and they say that if you buy a pass and don't like the plan when announced that you can get a refund up until late November. That seems more than fair so I committed to a pass.
I expect that most areas will be operating at a different level this season....or until a vaccine is introduced. I wouldn't count on food service, group lessons, pubs/bars....etc. I imagine that many will set limits on the overall number of people on the hill at any given time. I wouldn't be surprised to see lottery systems put in place to limit the number of people on the hill. I assume they will all require face coverings and will keep it to one person on a double chair and no more than 2 on triples and quads.
It's going to be 'interesting' to say the least.
