I was in North Park hunting Elk this year, a black wolf wearing a tracking collar came through the ranch I was on, one of the hunters and ranch managers saw it and took pictures. The guy put it on face book and the next day the game and fish was tracking it with a helicopter. It supposedly went over the mountains and dropped into Rocky Mountain national park. In my option Rocky Mountain National Park is wear they will start the introduction, they will grow into large packs wear nobody will ever be able to touch them and from there they will spread like wildfire. Believe me the man who was in charge of introduction of wolves in Idaho and Wyoming( Ed Bangs) lives in Denver Co. He has been waiting for this for along time.
