This is John Brown's Fort as it is called. It is really the old fire house where he, his two sons, and four other men were trapped when the marines showed up. It was probably a good thing they did because the town's militia wanted to hang him on the spot. Instead he was tried and convicted of insurrection, treason, and murder and hung. http://www.law.umkc.edu/faculty/projects/ftrials/johnbrown/brownhome.html There was some water in the barrels you see in the picture and James broke some of the ice out for the kids to play with. When we walked back by an hour later, the ice had refrozen.
