This week's Denver Cruiser Ride theme pays tribute to one of cinema's greatest masterpieces -- 1988's circus-centric Big Top Pee-wee
-- on the occasion of star Paul Reubens's birthday. Some riders got their Pee-wee on, as it were, while others let their inner animals out of the cage. Photographer Jake Shane was on hand to capture the action. Check out a sampling of his best shots below and click to see the complete Denver Cruisers Celebrate Pee-wee Herman and the Circus
