Colorado Laws

The flag of the state of Colorado

Every city is allowed to set its own laws, and Boulder is no different. That means, what may have been legal in your home town, may not be here. Ignorance of a law is not a valid defense if you break that law. So, here are some things that are crimes here, but may not be where you are from.
