We have a sinkable course in a cove, public lake. It has been there for over 34 years. I maintain it, which takes a lot of work and money. I only put it up early morning or weekdays that are quieter...but, people seem to find us, and I will pull anyone or teach anyone at their level. We have taught sooo many at our expense. Our public lake course got a U21 champion, and 2x junior master champion, and 4 national champs. But, did we grow the sport?.....Well not sure. People seem to take a ride or two and don't progress and don't go for tournaments.
We do have Trash Talk Tuesday in the summer, where skiers can ski and talk big afterwards at a large dinner we host. It is fun, but lots of work and time on the boat. Are we growing the sport,...Again, I'm not sure.
