Meadow Run

The large flat rock just to Jon's right has a fairly large void under it, with an opening next to the hole. It has been said to me that if a paddler gets stuck in the hole, he/she could get surfed under that rock. I have heard of some pretty good thrashings at this hole, but not a word about anyone actually getting surfed under the rock. Does anyone have an under rock or near under rock experience from Meadow Run's 7 ft falls? If so, what water level?
