My dad was an inspector at the plant. I would hear the warning beeper and rumble of the conveyor belt that ejected the culled sheetrock out the back of the plant, one sheet at a time, rumble...beep..beep...slide, thump, and I knew my dad did that...he tagged the sheetrock as bad, so they had to cull it. This picture shows me with my dog, Patsy, digging in the piles of waste gypsum near the USG plant.
