I have a log home in the very northwestern part of Loudoun County (between the hills) off of Harpers Ferry Road at 725'. My great room ceiling is 24' high and I heat with my wood stove whenever possible. My wall of windows faces west and I will get slammed with this frontal passage and will probably loose power - happens often. 75% of what I burn is black locust. When it gets cold, I really have to crank the wood stove to keep my propane furnace from coming on.
