I visited the moving wall at Travis air base a dozen years ago and it moved me deeply. I walked up and started reading names and it was a bit overwhelming. What got me was someone had left their medals on a small sign leaned against the wall with the the single word "Buddy". I choked up and could not hold it together after that. Recalling that still brings me to tears.
I periodically visit the one in Washington. I know where my fallen comrades are on it. I spend an hour or so talking to them there. It's a very appropriate monument to that war.
I have meet people who served. That was not my case and still the place with all family members morning their love ones is overwhelming to me. I certainly appreciate their sacrifice. I agree, it's very appropriate.
I've been to the one in D.C., but never seen the moving wall.
The erie feeling (and I mean this in the most positive way) it's pretty much the same.
