I’m from the generation before you- where it was even MORE dangerous.
DH says where he lived in upstate Pennsylvania, the boys would jump off of railroad trestles into the rivers and streams below — I stood on one of those bridges over the summer and looking down at how far it was it scared me to death - same feeling when I looked over the Golden Gate Bridge. I think DH jumped too but didn’t tell me.
He said one of his friends didn’t come up - body was found a mile or so downstream.
That was considered normal behavior in the 60s.
I grew up near the RR tracks. We would jump off trestles, play around the yards, jump freights to the next town.
We also swam in old quarries filled with water, some you would go to a high ledge where you had to run to clear the rocks below.
