Googling it and not finding a solid answer is quite the puzzle.Your thought about truckers striking in '79 sounds pretty reasonable to me. History's full of these hidden stories, and sometimes, these little keepsakes hold the key to unlocking those tales.Speaking of unique gifts, have you ever explored personalized gifts? They're like a way of saying "this gift is just for you." It's a neat idea to consider, especially if you're into the whole mysterious vibe of your new pin.
