History

Archaeological evidence shows that Boulder Valley has been continuously inhabited by Native American tribes for over 13,000 years, beginning in the late Pleistocene era. Throughout the Paleo-Indian, Archaic, and Late Prehistoric periods, indigenous peoples moved seasonally between the mountains and plains, taking shelter in winter along the Front Range trough where Boulder now lies. By the 1500s, the area was occupied by Ute tribes, joined by

Boulder Cruiser Ride

The Happy Thursday Cruiser Ride is a weekly bicycle ride in Boulder Colorado. The Boulder Cruiser Ride grew from a group of friends and friends of friends in the early '90s riding bicycles around Boulder into the social cycling event it is today. Some enthusiasts gather wearing costumes and decorating their bikes; themes are an integral part of the cruiser tradition. Boulder Police began following the cruiser ride as it gained in popularity in the early 2000s. Issues with underage drinking, reckless bicycle riding, and other nuisance complaints led organizers to drop the cruiser ride as a public event.

and a variety of state highways. Parking regulations in Boulder have been explicitly designed to discourage parking by commuters and to encourage the use of mass transit, with mixed results. Over the years, Boulder has made significant investments in the multi-modal network. The city is now well known for its grade-separated bicycle and pedestrian paths, which are integrated into a network of bicycle lanes, cycle tracks, and on-street bicycle routes. Boulder provides a community transit network that connects downtown, the University of Colorado campuses, and local shopping amenities. Boulder has no rail transit. Local and regional shuttle busses are funded by a variety of sources. Due in part to these investments in pedestrian, bicycle, and transit infrastructure, Boulder has been recognized both nationally and internationally for its transportation system. In 2009, the Boulder metropolitan statistical area (MSA) ranked as the fourth highest in the United States for percentage of commuters who biked to work, at 5.4 percent. In 2013, the Boulder MSA ranked as the fourth lowest in the United States for percentage of workers who commuted by private automobile, at 71.9 percent. During the same time period, 11.1 percent of Boulder area workers had no commute whatsoever: they worked out of the home.
