Where in Purcellville are you? I'm on Harpers Ferry Road about 5 miles north of Route 9 on the west side of the east hill. I did not lose power, but I was getting slammed with wind. I have a log home with a great room that has a 24' ceiling and a wall of windows that face due west with about 2000' of pasture in front of me. I had to go back to my bedroom in the back because the creaking was freaking me out. I'm at 725'.
