A few thousand boisterous bicyclists of Denver Cruiser Rides - many in "colorful" costumes - will congregate at several watering holes around Denver at 7 pm, then converge on the party location at Exdo Event Center, 35th and Walnut, for big surf/instro from the Royal Aces at 9:15.
A shot from one of the weekly Denver Cruiser Rides below...they can't use surfboards in downtown Denver, so they ride their bikes!
