Welcome to CO! I drive 470 every day towards the foothills. The part that you drive usually gets hit worse worse than the section I drive. Yes we can get clobbered at times, but it begins melting the next day. Roads are usually clear and dry within 48 hours. We had snow the last 2 weeks. How'd you do then? It will get worse. March and April are the snowiest months here. If a bad one comes we measure in feet. You've probably got some time to make up your mind. If your going up in the hills, snow tires would be a must for you.
