Mountain biking trails booby-trapped with nails in Colorado

After two mountain bikers noticed that their tires were going flat on a smooth section of the trails last weekend, a popular network of mountain biking trails just south of Denver was found to be boobytrapped by a series of 3-inch construction nails.

Denver native Tim Fishback was riding the newly opened Little Scraggy Trail in the Buffalo Creek Recreation Area over the weekend with his buddy Nick Kostecki when he discovered the three nails buried in the middle of singletrack trails, sticking upwards and with two-pound concrete bricks formed around them to stabilize the traps.

“I’ve never seen anything like it. Someone manufactured these things. It took some effort to dig those holes and put those in there and they were spaced out a good bit. Somebody was trying to do some real harm and they were targeting bikers,” Fishback told the Denver Post.

Fishback frequents the trails in Buffalo Creek, which were mostly built over the past two decades by mountain bike riders in conjunction with the U.S. Forest Service.

“That’s the craziest thing,” Fishback continued to the Post. “Mountain bikers built that trail. I rarely see anyone but mountain bikers on that trail.”

While the Forest Service said it will research the dangerous incident, it’s just the latest instance of someone sabotaging bike trails in a way that could have caused serious injury to cyclists.

In January, a Vancouver woman was sentenced to three years probation after systematically boobytrapping local mountain biking trails over a two-year period. And in March, trails in British Columbia were sabotaged with wooden stakes and wire strung at neck-level. A week after that incident, barbed wire was found at neck-level on a bike path in England.
