The lines blur where an eccentric hobby and defacement of federal property overlap. I'm sure at some time or another during the past decade you've come across a dollar bill with a colorful "Where's George?" stamped across it. You are then instructed to visit wheresgeorge.com so you can update that bill's journey. I'm sure many of you reading this have came across the now iconic red stamp on at least one bill in your days. So is this fun activity breaking the law? By federal law the people who have stamped that bill have committed an illegal act but to many across the country imputing this data has became a hobby. The purveyors of this illegal activity spend time and energy using cash only and putting stamped money into circulation to track these bills. So what's your take on the stamps? Do they really deface property or make the act of commerce more interactive? You decide.
