fishm@n, I live and hunt in Colorado. You're right, you do have to use a rifle tag here to hunt with a crossbow. This was on private land where they don't allow rifle hunters, so the bulls that I found there weren't quite so jumpy. There are very few people who hunt with a crossbow here because you have to share the season with rifle hunters. I hunted both private and public land during my season and found this guy on the private land.
