I went to Viet Nam 2 weeks after I turned 18 Aug 13,1966..Spent 26 Months there and returned CONUS on Oct 14, 1968. Beer & Cigs were indeed about 10 Cents each.

What really frosted my skinny butt was that when I got back I wasn't legally old enough to vote or buy beer or hard liqour ..

I've never gotton over the irony of that scenerio....
