That reminds me of a story. A fella from the city was driving through a rural area, when he came upon a 13 - 14 year old boy, dragging a log chain that had to be fifty feet long. The kid was sweating, as he trudged along, so the city fella pulled over, and offered him a ride. No thanks, the kid answered, that's our place about a quarter mile ahead. I'll be ok. The city fella asked how far he'd come with the chain, and the kid pointed over his shoulder saying; about a mile back that way. The city fella looked back down the road, back at the kid, and asked why anyone would drag a chain for over a mile! The kid replied........mister, you ever tried PUSHIN a chain??
