Cod

The USS Cod is interesting. Each sub is restored slightly differently. This one doesn't have big cutouts for tourists to walk in conveniently. You have to climb in the way the sailors did. Don't slip; you can wrench your shoulder. Don't ask how we know.

Ice cream machines were a much-coveted item. This one apparently was acquired through proper channels back in the day, and not via "midnight acquisition."

See it if you're in the area, but beware: Cleveland drivers seem to include as high a proportion of rude drivers as Chicago does.
