Damn Skippy.

As a kid I was chased into the Restroom at Yard Birds by some weird old guy who had followed me all through the store. He had me cornered, but took off when two guys came in behind him. That was in the late 70's-early 80's.

Back then, they didn't keep track of those 'dirty old men' (or women). They were just the 'guy in a trench coat' they told you to avoid. They also, in those days, told you to do whatever your Preacher, Sunday School Teacher or a Cop told you to do, no matter what.
It wasn't until the internet & sex offender registration (and the magnitude of Catholic Church Scandal) that people began to get an idea of how prevalent and dangerous those psychos really are.
