Years ago I worked for a large LTL carrier. One winter one of our drivers had dropped a 28' trailer at a warehouse for them to unload. The boss asked me to go get it the next day. We'd had some snow and it was melting then freezing. As I backed into the trailer, my drive wheels dropped over a ridge of ice just as the 5th wheel snapped shut. The ridge was only 2" high and 4" wide but I had to chain that cussed thing to move 4".
Getting stuck in a bad spot isn't like bending a trailer around trees and rocks, but it can sure get frustrating.
