I don't see area's setting up public racing venues even though the demand seems to exist in some areas- why not?? Because they realize they would be hauling injured folks off the hill on a pretty regular basis. I don't understand why the same thought process isn't there with the parks??
Even in what could be considered "public" race venues (Nastar) I would venture a guess that the safety record is far better than with most parks.
As for public racing, I do recall a few pay to play courses back in the early 80s... something like 2 bucks to ski a 45 second simple GS course with one liftie at the top and a time display at the bottom. I also wish they still has that
