Troofth. I had to go on Progress property once to pick up something for a friend. Just one of their maintenance facilities, not a plant or anything big.(Surplus stuff that he got dibs on). Had to have a safety briefing because a forklift was involved. That took longer than backing in and loading. And three people present, but I had to have a guide walking behind me to back the trailer. Some other dumb, but effective stuff to pay attention too....they take it seriously.
