Put this down under Things Learned While Walking. While walking this evening (er, last night), I met a major supporter of Rocky Mountain Honor Flight, a foundation that takes surviving WWII veterans on a weekend trip to DC, to take in the new WWII memorial, the FDR memorial, meet with former Sen. Bob Dole, and generally see the sights. These guys came home to a job market and a housing market that had adjusted to their absence, and had yet to readjust to their reappearance.
Our war memorials pretty much got built in reverse order, with Vietnam and Korea coming before WWII. (I know it was the first war with an integrated military, but I wish the Army didn't feel it necessary to point out the race of the soldiers depicted therein.) With only one surviving WWI veteran, it's unlikely that we'll ever see one to those troops, although DC does sport a memorial to its own WWI vets and a memorial to the AEF, with a statue of Pershing and some pretty neat color maps of his effect on the Western Front.
Rocky Mountain Honor Flight is part of the national Honor Flight organization, so if you're not in Colorado, consider helping to underwrite a flight, or starting a local chapter in your state, if it doesn't have one already.
