If that's true, it would be a pretty lame reason. If someone is going to sue for their own ineptness, or, scamming for money, having a nice smooth sandy slope isn't going to stop them. They could sue for any goofy reason......tripping on some steps.....cutting their foot on a shell...... bad sunburn.....etc. We have rocky cliffs out here in places and some people have died trying to climb them or jump off of them. We don't close the beaches because a few idiots want to risk their lives.
