Participants navigated the waters of Boulder Creek, turning the waterway into a temporary transit corridor. The event is designed as a community gathering where the act of traveling to a destination is prioritized over the destination itself. The scale of the event saw hundreds [1] of individuals joining the flotilla, creating a visible spectacle along the creek's path.

Organizers and participants faced varying water conditions during the commute. Reports indicated that the event returned to a low-flow state of the creek, which created a more rocky ride for those in tubes.

The tradition serves as a social marker for the city of Boulder, blending the town's commitment to nature with its professional life. The event encourages residents to step away from traditional vehicle-based transit and engage with the natural geography of the region.
