Thanks for the update JimBlay. I couldn’t tell precisely from your photographs, but is the concrete pad in the second photo the place where the west side shower is/was located? Are the showers still in place or have they been removed?
Shower is still in place. It is back and to my right in the photo you referenced. That pad is where they used to have trash or recycling bins or something like that. I don't recall exactly what used to be there. But the shower is definitely still there because I used it!
