Some good lols there.
We've got huge traverses at my home hill and others I've skied at. Good snowboarders make them work, and it can be frustrating to go around people that don't have a clue, but I wouldn't tell them to get off the mountain.
I spent years getting turned away from skateparks because I was on a bmx bike. Can't say that I'd ever want to bring that sort of discrimination to Alta.
And I won't be spending my money there.
