The bizarre event does not actually originate from anti-Amtrak sentiment, but from a bet that a local drinker made some 30 years ago that he would buy a round for anyone in the bar who would flash themselves at the next passing train. It’s now turned into something of day-long fiesta with hundreds of people lining up against the fence and dropping their pants, with trains slowing down especially on the day.
