Report 69433: Possible Sasquatch wood knocks heard near Masonic Monument along Blue Ridge Parkway

Barb and I travel the road off the Blue Ridge Parkway to the Heintooga trail several times a week when it is open. We are flower & wildlife junkies. Apprpx one year ago we were at the pull-off just before the Masonic Marker looking at Fire Pink flowers when out of the blue there were three tree-knocks from across the road. Very loud & distinctive. There was no one else around whatsoever. No wind either. We have noticed rocks that have "fallen" down the mountain & landed on the roadway but no sign of where they had come from also. Thanks, C.Z.
