With seasons seemingly getting shorter and/or worse (due to what I assume to be global warming) and the lines just getting absolutely ridiculous [1], I think I've accepted the fact that skiing/snowboarding is going to be a different experience for my kids. That experience probably won't be at a traditional mountain like Killington, Vail, etc. The lines will be too long, too expensive, just overall it will suck. Hones…
Leave the US.
I worked at a mountain in the US where it was quite normal to have a line from 30 minutes before opening until after closing. I would load passengers on every single chair, all day, every day.
I moved up to Canada. It was quite common to go 15-20 minutes without a single person getting on my lift. I regularly ski runs and don't see a single person for the entire run. I often only cross/see my own tracks.
Leave those crowds behind.
