Monday, November 9th, Remnants of scary things

The weather this weekend was absolutely glorious with temps in the 70's, blue skies and gentle breezes. Since the house already felt stuffy because the furnace has been on for a month, I opened some windows to let the Indian Summer in. Front and back door open to get movement from North to South and then family room and living room window open for East to West. Well, upon opening the living room window, I looked up and saw this:
That's an entire sheet of cobwebs at the top of the window....icky!!!
I promptly got out my swifter to nab it....it's gray, meaning that it's been there for a looooong time! Guess I need to look up more when I clean.
