When I was at Takhli, in Jan of '69 the temp dropped into the mid/upper 60°s. The Thais were ripping off blankets and sheet from our hooches. I was so acclimated I was miserable, . Didn't even have a long sleeve shirt, just a thin raincoat, which I kept under lock and key when I wasn't wearing it. Groups of civilian workers would stand as close to the frag arming area as they could get, to warm in the Thud and B-66 engine exhaust. Was strange. Nice and warm in the screen room, however, since most everything then was still tubes or hybrids...
