The tire next to the shitter doesn't have the same pizzaz as a stripper pole, but interesting story behind that one if you could find someone to tell the tale.
I imagine the numbers on the wall had to do with that assigned to the livestock or lots for tracking purposes, but that's just a guess.
I can't always find the history, this one was quite easy and has lots. I would imagine that long part is where all the work was done. Must have been cramped sleeping conditions.
