RE: 3D & Hovering Guidelines in Your Club
In another thread there is a great wail of no rules because good folks use common sense. As I am sure you have heard, sense is not common. However, rules are a poor substitute because we are made up of folks who blindly follow the rules, even to death in some cases, and those who intentionally break them. The problem, in this case, is that rules will not fix a lack of attention or failure to think. Rules are not fixes for problems rather they should be guidance for operations.
From your description, you and the club have already provided the guidance. My complements to you for the attempted go around.
