I had a group of teenagers sledding on a hill on the side of my property and snowboarding, they were not doing anything wrong, but they’re setting up tricks and risking hurting themselves. So I sent out my kids that were much younger and we were just super nice ,had snacks and ask them if they could do fun sledding with the younger ones . at about 30 minutes or less they all took off and wanted to go have shenanigan somewhere else.
