You should be fine with concealed carry in any area of the state. The only part in limbo right now is the National Parks. That is being fixed as we speak. The places to watch out for as far as open carry goes are Denver and the Denver Mountain Parks. These parks can be miles from Denver but are technically part of the City and County of Denver and so open carry is banned. Check out handgunlaw.us for links to the laws. Don't just take their word for it. Read the laws on the linked sites or search for them. Colorado law and Denver law are both available on the internet.
