Really? I didn't know that. I figured it would be much more difficult to back up a tractor-trailer. The very thought of it makes me cringe. I can back up a small trailer -- another thing my father taught me. One day I was parked behind a store, getting boxes from a cardboard dumpster for moving. This truck pulled up and was trying to back up to the loading dock. He must have been inexperienced because he backed up and pulled forward for -- I swear -- like 10 minutes trying to line the truck up. After seeing that I figured it must be next to impossible to back one of those things up and make it go the way you want it.
