I had about 45 minutes before I had to meet some friends so I decided to venture into this museum and check it out.  It was free and had A/C so those were another two pluses.  The front desk people were really nice and helpful.  Note that if you have bags/a backpack, you have to leave them upfront.  \n\nIn terms of exhibits, you can learn about Wisconsin soldiers throughout the years:  the Civil War, WW I, WWII, and up to the Persian Gulf War.  I found the Civil War section to be particularly interesting -- I learned more about Wisconsinites' stance towards slavery.  I also enjoyed the media exhibits where you could hear Wisconsin soldiers talk about their experiences -- I think that was in the Vietnam war section.
