ShadowBeardie123: Well- I saw the note from GeoNico19, saying he saw a burned out tree at GZ that looked like it could have been my cache host. So I thought I'd better go and check this out.
When I arrived at GZ, my fears were confirmed. The whole side of the tree was burned from bottom to top, and all over the insides of the tree. I'm not sure what would have caused the fire, but my guess would be a lightening strike.
So- this marks the end of this version of the Hobbit Hole. It was so much fun while it lasted. Time to move on. I attached some pictures of the burn with my phone in case anyone is interested in seeing the damage.
