Yup, I've experienced the wake boarders, and their huge wakes. We have them all over the place here. I've seen those wakes do quite a bit of damage to floating docks, not to mention the boats tied to docks, as well as erosion and other damage to the shoreline. I suspect, and hope, they make those boats and activities illegal someday. Lakefront home owners are going to unite and do something about it sooner or later.
Oh, and just see how much fun it is to hit one of those rogue wakes out in the middle of nowhere while doing 70+ mph! Not fun!
