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.
The other was somewhat more successful at flattening against the structure.
Yeah, back in the day I used to cross a trestle over a river a couple of times a summer. This was actually a Boy Scout thing. Some of us got seriously into hiking. One of our natural point-to-points had this dang river in the way. It had, of course, a quite convenient trestle. We took care to take care. Still not the smartest thing I've ever done, but good memories. It was fun at the time.
