I was a 17 year old boy once. Yeah, we played around train tracks. We didn’t lay down and drape our feet over them ... and we damn sure kept our eyes and ears open. Trains big and loud and will FXXK YOU UP if you don’t respect them.
We played around TRESTLES. Would get in the middle of a trestle and run like hell at the last minute to get off before “too late”.
Actually, I can remember doing that once. I was young and dumb then. But not that stupid. I was pretty chicken. I made sure I got off like a minute before the train even got to the trestle. I thought; “Jeez, this is (bleeped) up. Not doing this again”.
And - since I’m still alive - I never did.
