My husband retired from the USAF in 1982, and we just celebrated 40 years of marriage. I got him the Sentigram as an anniversary gift, and he tells me he loves it. Putting in the pins evoked lots of great memories and war stories. As he shows off the map to his kids and grandkids, they ask about this pin or that place, and he remembers ... and tells them all the details! Thanks for a great idea.
