I think @RazorRoss3 is exactly on point in talking about collegiate skiing and a registry. That would be great. I was an open water skier before college, but got absolutely got hooked through my team competing with NCWSA. Since then, I have been constantly searching for places to ski, but it is difficult (1) to find lakes with slalom courses, (2) sometimes cost prohibitive for recent grads to pay annual memberships if $50/$60 per set, and (3) not realistic for many to buy a boat right away. That unfortunately leaves myself and many of my former collegiate teammates on the outside looking in.
A more thorough registry would be a great idea. I know that I have used wakescout at that is certainly helpful to a point, but I'm sure there are plenty of lakes and clubs it is missing.
