When I was young, we belonged to the Peninsula House Beach Club in Sea Bright. Great place for a kid to grow up in the Summer. Burned own while at Rutgers.I believe several Monmouth University students died being buried alive in a fraternity hazing incident on a beach. Basically, digging their own graves as the holes were too close to each other and collapsed. This happened several decades ago.
If memory serves (didn't look it up) I think that happened next door on the public beach.
