From the article:
"That's when I met Jimmy Q, an explosive ordnance-disposal expert back from Vietnam. Jimmy was typically seen in a cut-off gray sweatshirt and mirrored aviator shades and lived in a one-room apartment over his gun store. He was also the first for-real "combat shooter" (that's what we called it back then, combat shooting) I'd actually met."
MB, is this Joe Pike?
