Moderately surprised they don't move more of these museum ships into the Great lakes because of the reduced maintenance costs from fresh water. I heard the cooler temperature helps too. Every once in a while I end up in the neighborhood of the St. Mary's Challenger, still in use as a barge after being launched in 1906. We also have a couple of Gato class subs and a number of tugs. The Iowa class ships are a bit large for the seaway, but it would be nice to think about how much more these museums could do with a larger budget.
