I'm sure many of us have done things similar to those that Gutbuckteer, but don't start on that "overprotective parenting" crap. Being cautious and teaching kids not to be as stupid as we were is something that more people should be doing. Just because one person was lucky does not guarantee everyone will have the same results.
We used to play on the railroad tracks as kids. Until one kid did not see or hear a train coming and was too paralyzed with fear to get away in time. Would you like to tell the parents of an 8 year old that their child was ripped apart by a train? We can laugh at the mischief we got away with, but that doesn't make it right.
