My brother is from South Vietnam.  He was on THE LAST PLANE the day Saigon fell.   I always thank vets when I see him.  I have yet to even go to DC, let alone the wall. 
But it is like I told my wife.  She said "Well, take some Kleenex".  I replied "Nope, (said sharply and fast)".  "Why not?"  I said  "If the amount of water leaving my tear ducts can make a buddy's flower last 30 seconds longer, it is worth it."  She cried her bellybutton off. 
I was wondering though, is there a guy that has either dog tags or bracelets of MIA's?  
Midnight, thanks for the pic.  I love looking at pictures of the wall.  Thanks
