Photos, video: Boulder commuters float to the office on Tube to Work day

A few commuters in Boulder may be showing up to work dripping wet because of their participation in Tube To Work Day.

The lighthearted holiday hits seven years on Tuesday. It began as two men tubing to work along Boulder Creek in 2008.

Last year it saw almost 30 participants, some wearing wetsuits and some wearing business suits.

The event typically takes place in June to line up with Boulder's Bike to Work Day. But the Daily Camera reports that safety concerns because of the volume of water forced it to be pushed to July this year.

The city of Boulder is sponsoring a breakfast station off the creek. The public is invited to participate, but commuters must bring their own tubes.
