Was at Horsetooth yesterday getting ready to ride when the police/rangers/SWAT came charging into the Soderberg TH and asked everyone to leave. We were not allowed to ride Horsetooth and went to Blue Sky. While going up the trail from Soderberg to Bluesky we noticed rangers blockading the road and guys in cammo with assault rifles. We asked multiple authority figures what was going on without any answers. Didn't see anything on the news. Anyone know what was going on?
