I spent several of my prepubescent years in Springfield, Mass. When I was 8-9 years old, my best friend and I used to fuck around hopping freight trains as they went by...once, just after we got on, the train picked up speed and we ended up on the outskirts of Boston before the railroad cops caught us...and called our parents. His dad was an ex-cop...and came to pick us up. He beat the shit out of both of us...then when we got home, my dad beat the shit out of both of us. We promised to never do it again.
Needless to say, we were back hopping freights the next week.
