This is a photo of Joe taking a quick break on a patrol in the rubber near Loc Ninh in November '67. The red clay that we dug and lived in added color to all of our clothing and gear.
"Intense" isn't a powerful enough description for his expression. The "thousand yard stare" says volumes about the cumulative stresses Joe had acquired throughout his tour as well as what we had been subjected to during Oct-Nov.
