Will I be extradited from the east coast for a class 6 felony warrant?

It is possible to be extradited on a felony and even some misdemeanors, but I would suspect this is a low priority, as you suggest you might call the court clerk for the county from where the arrest warrant originates - ask these questions to him/her often, they need you to appear in the state of Colorado to quash the warrant and set a court date. many times, a prosecutor will not even discuss a case until the warrant is quashed. But, it depends on the county. A lawyer may be able to help you accomplish all this so that when you do appear in Colorado, a deal is ready to go and you can handle everything in one trip. Good luck.
