There is usually an event with some slalom pros teaching those that would like to learn, I believe put on by Russell Marine. They had a Pontoon boat on the entrance with a large sign saying IDLE SPEED ONLY! The Ski Club location is called Porter's Branch. I checked it out last year and was impressed at a few kids that I saw skiing the course. Below is the link to the event from last year. I also found the link for the dates for this year as well. It looks like they will have a couple of wakeboard and surf clinics for those interested.
Mark, they are still there for sure. It should be nice too as the water level is near full pool.
