You might want to invest in some studded tires and a cheap MTB to mount them on. Last year there were only about 6-8 days where I didn't ride because of ice.

This year was geared up (if not entirely prepared!) when Wintery stuff hit a couple weeks ago. Already matched last year's total of not riding through the entire season because of ice. This year, being ready with the tires allowed me to ride!

CO weather can be wildly unpredictable. Winter was a dry one here last year- a more "normal" season can see us getting plenty of snow. Match your equipment to your determination to ride.
