Even before the Internet!
Just before our first trip, I went to get a haircut. And I had this old-fashioned barber. "Any vacation plans?" - "Yes, we're going to Disneyland!" - "Ah... they've abducted children there, you know?"
That's when I started learning about Urban Legends, and I learned not to trust them. I'm glad I found snopes.com back then (which adresses that issue as well).
