@crosscountry wasn't thinking so much my local hill in NM where they still scan the old school way.. but an example would be Winter Park CO. You go through RFID gates for the lifts at the base area. But once you are up on the mountain all the upper lifts have no scanning. Presumably anyone who got that far up can ride for free. (You could game it by skinning up to that point I supoose) To install rfid gates at all those secondary lifts, some of which get long lines as it is on weekends and holidays, would indeed cause congestion. There isn't that much space at some of them and the cost of that infrastructure would be prohibitive. If they sold an AM pass, there would be no way to prevent someone for paying for the morning but skiing all day. I think this might apply at other mountains that have multiple lifts that don't go to the base like Steamboat or Telluride or Vail.
