My first exposure toTx A&M was in1966 AnKhe Rep of SVnam- 70th Engr. Bn. All Plt Ldrs were A&M, CoCmdr and Bn Cmdr tu. Didn't know about the rivalry and they didn't talk about it in front of the EM.
The Wall is cool. I was part of an organization that sponsored it in Killeen several years ago. I was helping people find names when a lady asked a co worker to help her. She had a letter returned and she had kept it all those years. The co-worker looked at the name and told her the name was not on the wall. She asked him how he knew and he said "Because it's me." She had got the name through one of those "Write to a Soldier" groups and he had responded twice during his tour.
