Has anyone ever heard of that? Not trying to be funny here. There's this cattle barn near Herr's potato chip in Nottingham PA that is over a hundred years old and is now a flea market. Its gorgeous. One of the guys up there pointed out that there were no spider webs / cobwebs. I took note of it and said its a very nice barn! He says, It's self cleaning. I laughed and was sure it was a joke of some sort. I think he was saying it had something to do with the ventilation...anyway, whaddaya say farmer folks?
