Next time you visit Arlington, or maybe another national cemetery, here's an interesting and informative clip about the origin of the headstones. Somewhat moving as it's highlights the loss of the last WWI survivor.
Agree with you on what an experience it is to go to Normandy, An easy drive, by the way from La Defense Ren., for those that want to do the day trip and return. About an hour and a half from the hotel. Very nice, inexpensive places to dine along the coast of Normandy.
Thanks so much for your comment.
