>> In all those years I was never even approached by a stranger.
I was, during my elementary years in the mid 70s right outside the school property. I remember it well. I declined the offer for a ride home. A police report was filed but nothing ever came of it as far as I was told.
Except that a few days later you saw your dad cleaning his shotgun, and you knew he hadn't gone hunting or to the range recently.
Parents like to keep the nasty details from the kids. :)
