I remember flying on a PanAm (MAC Charter)from Yokota AB, Japan, INTO Tan Son Nhut AB, Saigon, RVN in Jun 1967. Crisp new $20 bills which wilted before our very eyes while standing in line to exchange the US Currency for MPC.
LOL!
Was some kind of a shock wasn't it?
Oh that heat. Especially during Monsoon season.
Take a (luke warm, or whatever temp the water was from a 50 Gal drum) shower, put on a clean shirt and within moments of stepping outside, one was covered with sweat and your shirt clung to your back.
Of course when not working, that gave us a good excuse (as if we needed one) to head to the closest (Air Conditioned) Watering Hole and have "beaucoup" (Formaldihyde laden) 33 Beer.
Seems like you were just coming, when I was going.
Stay well, stay safe, Welcome Home my brother and God Bless.
