A policy like this would be impossible to enforce at any resort of significant size. Maybe at some mom-n-pop hill where they can be more like a club. They'd have to put "rut police" all over the place and pull over anyone making a line. Skiers, good softbooters, telemarkers, snowbladers, whatever. If they were to ban hardboot alpine snowboarding, personally I would go get a metal BX board, some Flows or FR2's, stiff softies and rut the krap out of the joint right under every chair. Then I'd go get some SL skis and do the same.
