Cottonwood, MN, farmer Harold Fratzke's Wagon Hitching Mirror is an 8-inch convex mirror on the front of his wagon. Three strips of reflective tape affixed horizontally across the mirror help him gauge distances and know exactly when to stop his pickup truck for hooking up the wagon. To set the mirror properly, he sits in the truck with the wagon hitched and has someone adjust the mirror until the middle strip of tape lines up with the pickup's bumper.
