I think the jump is your biggest liability there. So if your community has decided they are going to tow....then towing is towing. there are many variables for all sports and activities that could arise, that could result in a lawsuit...so I don't think tubing is the problem. I know a private site that has created "dead zones" at either end telling the drivers to go to 0 about 150ft from the ends which doesnt impact skiers much but i guess it takes some of the fun out of it for a tuber..
