Its been so long ago but I suspect that my first "out of town" headshave was probably on a field deployment either at Fort Lewis, WA or over the Cascade Mountains at Yakima Firing Center, WA for training. I use to shave everyday either out of(back then) steel pot or mt favorite, one of the HUGE institutional sized fruit cans from the mess tent filled with water and heated on a white gas stove. Had some great shaves on hot summer days under my camo net.
