I never would have thought of replicas of the Vietnam Wall, much less that there were traveling exhibits of it. But GovExec has an article on the replicas, and DOD"s RFP for another in preparation for the 50th anniversary of the war. I'm not sure what they're using as the starting date, certainly the first person on the Wall preceded 1966. Thanks to wikipedia we learn it was 10 years earlier, and he was killed by "friendly fire", so to speak. A fitting opening to a very complex and confused episode in history.
My personal 50th anniversary won't be for another 16 months or so.
