I had a patient last week with a belt buckle exactly like your tattoo from last summer's trip. He was a career guy with something like 52 months in Vietnam between '60 and '68, and someone had handcrafted the emblem into buckles for he and some of his buddies years ago. He still wears it every day. He thought it was kinda neat that you had the tattoo, but he wanted to know why you weren't signed up if you like it that damn much. :D
