It is a Sadoff dumpster...which if you wanna guess is exactly where I take 90% of my metal. I get better than yard prices because of the materials I bring them on occasion so I cannot burn this bridge. It was too good to be true. That said, I talked to the manager and he said anything I find in the dumpster that I want is mine for the taking so I will continue to pull shelving out when I see it, so it's not all lost.
