A quintessentially Boulder event, Tube to Work Day returned for its 12th annual aquatic commute Friday, July 19. Tube to Work Day began as a challenge between two friends to commute to work without using a personal vehicle. It has since grown to include around 1,000 commuters. This year the event was partnered with the Boulder Bridge House, a local charity focused on ending homelessness.
