Internal-combustion equine........

I live in Lancaster County, Pennsylvania. The sight of an Amish buggy almost never turns my head anymore because it's just part of the landscape here........but yesterday I saw something I'd never seen before. There was a horse and buggy parked and tied to a gas-pump at a service station. It seems that the Amish have been quietly developing hybrid technology............I'd bet it still only develops one horsepower.
