I received this email:
My name is Ron Raymond, a former member of Delta Co., 6/31st. 68/69, who just happened to be informed of your great website.  Out of all the pic's you show there's one that has a familiar face. On the 'Moore' scene of pic M1 there's a group photo with a Tiger Scout walking through the background. A name for that face is 'Hai'. He was assigned to our platoon and was the oldest of the three scouts.  I think he was roughly about 50 years old at the time. He taught me how to survive & eat off the 'Delta' out in the boonies during my time as a grunt.
