There are quite a few traditional bowhunters who have killed bighorn sheep in Colorado. Several of them more than one. But these are residents who are have a much greater chance of drawing a tag than non-residents. I moved to Colorado 30 years ago and have drawn 3 bighorn sheep tags. I killed a ram in 2003 with my 3rd tag. On the first two tags I never go close enough to get a shot. I have been putting in for desert sheep the last 12 years with no luck in the draw. The chances are that I will never draw a desert sheep tag. I do know a couple of people who have drawn non-resident Bighorn tags, but it is extremely difficult to draw a non-resident tag. But as the saying goes, somebody has to draw these tags and you only have a chance if you put in for the draw. Good luck on your quest. Jim
