When I was in 8th grade I lived by these train tracks. I used to cross over them and go to my buddys house to play video games (freshman year this became video games and weed smoking). Freights used to stop on the tracks all the time and I would just climb over. One day there was a freight stopped and I decided to climb under it, while I did this I heard a noise. Once I emerged on the other side the train started moving. I stood there for five minutes copletely stunned and never tried to go over the trains.
