After the 3.5in rain and lightning storm, I expected some road damage, but nothing like this! I noticed one tree, not far from the shop, that seemed to have lost all of its bark on the main trunk. When I got around to look at the back side there was a gaping hole where violent twisting seems to have popped oout a big chunk of wood. This tree was not showing any signs of distress and no other trees on the lot have any damage like it. It's as a small twister or some freakish wind did it in. I put the piece of wood back (3rd pic) in, sort of, so you could see the trunk was rather smooth, but the piece doesn't really fit any more. UPDATE: I found bark from this tree 75ft away - it must have been violent!
