CARBONDALE, Colo. - Two more booby-traps have been found on mountain biking trails in Colorado.
The Glenwood Springs Post Independent reported the boards were found on the Creekside and Skillsaw trails in the Prince Creek area.
Cyclist Colin Osborn told the Aspen Times he found both of the booby traps Sunday.
The federal Bureau of Land Management says one of the boards was found on public land and one was on a section of trail that crosses private land.
BLM spokesman David Boyd says no other incidents have been reported.
However, 7NEWS reported last month that a strip of metal spikes was found on a trail in the Rampart Range area, south of Denver.
"The wire spikes were buried in the trail bed so that wheeled vehicles would be damaged and unsuspecting hikers could be injured," according to officials with the Pike National Forest.
