How do most private sites deal with the liability of non ski related lake use? Do you allow owners to pull tubes? (probably the most dangerous) We have a community boat, but owners also have other options to tow tubers. (personal jet skis) Lake is large enough, but you do have to pay attention at the ends that you don't throw someone up on shore. Some owners are afraid that they may face a law suit, even if they are not in any way involved with the activity.
