We were visiting my Mom at the nursing home, where she is now convalescing from a small hip fracture--While sitting in room, things started vibrating--chairs just vibrating Dale's water bottle, which was on the floor, fell over, and a few drawers of a dresser opened--Thought at first we were in need of an exorcist!! The whole ecperience lasted for less than a minute, but was quite interesting, for sure.
When we got back home and i went down into the dungeon to do some painting, i found that five quarts of paint had been dislodged from the top of a now dead air cleaner and weree on the floor. Yes, in Delawhere, we felt the earth move under our feet!
