BOULDER, Colo. – A large crowd turned out in Boulder Wednesday morning for the annual “Tube to Work Day” event.
This was the 11th year of the aquatic commuting event on Boulder Creek, which kicked off a little after 8 a.m.
In line with past years, many of the participants this year donned goofy costumes and some even wore business attire like a suit and tie.
