I just remembered something from a long time ago, when i was into mountain biking in Vancouver, B.C. (early 1990s), and wondered if it was actually true.
At that time (and still now i guess), there was conflict between mountain bikers and hikers. Mountain biking was new, and many hikers hated mountain bikers, claiming that they destroyed trails and were dangerous and inconsiderate to other trail users. Bikes were not allowed on many trails, but bikers used them anyway.
The conflict sometimes got ugly, and there were stories of booby trapped trails. The most horrific were of thin piano wire being stretched at face level between trees on downhill sections.. a biker would be decapitated or have their face torn off if they rode into the wire at speed.
At the time, my friends and I took this to be true, and somebody knew somebody who knew somebody who was horribly disfigured by evil militant hikers.. It occurs to me now that if this was really true, a much bigger deal would have been made out of it.
Has anyone else heard of this, or was it just a regional urban legend?
