I haven’t been to the G. I. Museum in Ocean Springs, Mississippi but it looks like interesting. You can visit their website at http://www.gimuseum.com/.
Admission and Hours: http://www.gimuseum.com/?page_id=26
The GI Museum is a non-profit establishment so visitors are welcomed to tour at no charge, but donations are welcomed. The museum is open every Wednesday and the first and third Sunday of each month.
