I don't know what the solution is but I agree that something needs to be done. The only way I really see it working is all parks having dedicated lift access with lifties that actually check for park passes. Last year Gunstock had bright orange construction fencing with a two foot gap in it at the top of the park entrance to ski through which helped a little bit, but stuff like this still happened. This kid could've been beheaded if he was about five feet to the left.
This year the fencing is gone and it's only worse, you can barely make it to the bottom of the park without getting cut off on the weekends.
