Colorado Revised Statutes allow unlicensed vehicle carry
"CRS 18-12-204(3)(a) A person who may lawfully possess a handgun may carry a handgun under the following circumstances without obtaining a permit and the handgun shall not be considered concealed:
(I) The handgun is in the possession of a person who is in a private automobile or in some other private means of conveyance and who carries the handgun for a legal use, including self-defense; or
(II) The handgun is in the possession of a person who is legally engaged in hunting activities within the state."
I don't understand the logic of states that permit handguns in your home or on your property but not in your vehicle.
