COLORADO SPRINGS, Colo. (AP) - The U.S. Forest Service is warning hikers and bike riders on Rampart Range trails that spike strips have been found hidden underneath trails in the Pike National Forest.
Forest officials say strips studded with nails were buried in a trail bed so that wheeled vehicles would be damaged and unsuspecting hikers could be injured.
A warning posted on one trail said the hidden spikes caused five flat tires on three bikes and one rider suffered an ankle injury.
The Forest Service is asking for help finding those responsible.
