While I don't know what one's fair share is I do wonder if anyone, parents, teachers, or friends ever suggested the potential dangers or were you able to figure that out on your own and conduct your share accordingly?
I think your comment was meant for me.
Yes, of course, parents all warned against crossing the railroad trestle over the river, which was long enough and high enough to be scary. (If I recall correctly, there were a couple of platforms on it for the safety of railroad workers who might get caught on the bridge when a train came.) This was in southern Indiana in the 1950's, and we also had old limestone quarries in the woods with sheer 40 foot walls that were perfect for little kids to climb. We were warned against that too. Just like we weren't supposed to go down into caves. But since our parents had all taken the same or similar risks when they were young, they accepted it as a part of growing up.
We never lost anyone, but we did have a close shave when we were cornered by cows. We were moving along a creek bank on the edge of a farmer's field. The cows came over the investigate. Cows are pretty big when you are pretty little, and none of us were farm kids who were comfortable around big animals. We took shelter behind the trees on the edge of the creek. The bigger kids could swim across but the really little ones -- they might have been five or six -- were too scared to do that, so a couple of the bigger kids had to swim across and go fetch a parent. We learned our lesson about not taking little kids along when we went exploring.
Wrong guy, you want spinks
