An estimated 1.8 million Coloradans will be traveling over this double-whammy holiday season, putting an exclamation point on a record-breaking year of travel for the state. AAA Colorado’s numbers — covering the holiday period starting Saturday and running through Jan. 1 — include travel by planes, trains and automobiles, as well as other forms of transportation. This year marks the ninth consecutive year of rising holiday travel by Coloradans, according to AAA, North America’s largest motoring and leisure travel organization.
