We visited on a Friday and there happened to be schools visiting. As part of their field trip, the fort had it's staff "training" the military recruits, so we got to tag-along and learn as well. If they happen to be doing this when you visit, I recommend tagging along as well - they welcome it! They also did a real canon firing demonstration - very cool to experience. They also have a nice collection of old Civil War memorabilia within the fort on display. It is located right on the river - you really get a good feel at what it might have been like back then. And it's a pretty cool sight to see the big cargo ships go by!
