If a Patroller comes along and sees people standing in a dangerous spot they will stop and educate them. However, in most cases the problem is long gone by the time a Patroller gets to a reported problem like this. I find a really close high speed pass tends to get them moving along.
Yes, that should get them moving pretty quick. Lol. However, Ski Patrol should set up so that the area gets constant patrol and keep the area safe.
The protocol of Ski Patrol is safety as their first concern. Hence avoiding injuries.
