We went with a cryptologic expert who was able to explain so much to us. I was so impressed with the amount of material the museum had on display. Definitely takes around 2 hours- more if you like to read everything.

Off the normal tourist route, this museum is full of "code talker" & encryption history. About 20 minutes south of Baltimore, the museum is free; takes donations. Suitable for younger visitors since it has many interactive, hands on stations. There is an actual cryptograph from...More
