Nah, nobody in Memphis wakeboards!
Actually, there are a bunch of people who ride, but nobody I know is still going at it now. Ski Freeze (which does include wakeboarders, despite the name) is coming up soon, so check that out, and support a charity. Stop by the Memphis Boat Center for more info, and to find out more about the Memphis scene. It is off of Getwell, off the 240 loop.
