Last year one day, I was cleaning up inside the barn, and decided to load up the back of the pickup with scrap steel. As I started off to the scrap yard the next morning, I happened to recall one small box of scrap aluminum that I had tossed up in the loft, and had forgotten to take before, so went back to get it, and sat it on the seat beside me. Lo and behold, I ran across the scales, unloaded the steel, ran over the scales again, walked in with that box of aluminum under my arm, and walked out with more money for the aluminum than for something like 1,500 lbs. of steel. No real surprise, but that trip sure drove the point home.
