In Utah it's illegal to carry a firearm while on an archery hunt, unless you have a concealed weapons permit. Not sure about Colorado but make sure you know the rules their before packing a firearm on an archery hunt.

But like others have said this is an extremely remote problem. I've personally never worried about it although I was stalked by a black bear while calling elk in camo and sitting down under a tree. I stood up and waved my arms and once he realized what I was he turned and ran the other direction.
