Just caught up with this thread Duke, excellent photos and scene as is usual :salute::
About Water Buffalo's, of the little I've read in biograhies of US troops encountering them up close, they didn't seem to friendly, and quite often came of worse for the encounter and the troops being fined to pay recompense to the Vietnamese Farmers.
But then just your usual cows encountered out in a field can turn out to be quiet offended by human presence !
Though I remember a couple of years ago when work to me to a small Dairy Farm and stroking some inquisitive cows over the fence who were all very friendly licking my hand. After the Salt I guess !
