Hi Ballers - We just set up a ramp in a public area, and we're looking for ideas on how to prevent people from using it who are not vetted by one of the local clubs. We also need to keep jetskiers from using it. Probably something that's locked to the jump surface and visible at a distance. Ideally, it would be lockable, easy to remove and replace, and easy to keep out of the way during jump sessions. Also -- and don't kill me for asking, please -- will it damage the ramp if wakeboarders use it? It's a glassed plywood surface.
