BOULDER, Colo. (AP) - Some people in Colorado are staying cool on their commutes by tubing down a snow-fed creek.
Friday's 12th annual Tube to Work Day in Boulder comes on a day when the temperature is expected to reach 99 degrees.
The Daily Camera reports that 1,000 people are expected to participate in the event aimed at promoting alternative transportation. Organizers bill it as the "world's greatest traffic jam."
Television helicopter footage showed people going through mild rapids as they made their way down Boulder Creek in tubes, including some dressed in suits. People gathered on bridges over the creek to watch.
The event was delayed this year until the water subsided to safe levels following a winter of plentiful snow in the mountains.
