A strange 1926 photo, from gnotalex's photostream at Flickr:

Members of Cañon City Klan No. 21 pose on and around the ferris wheel at the site of a carnival at 8th and Greenwood in Cañon City, Colorado. Klan members were invited by W. H. Forsythe, owner of the outfit and a klansman from Fort Collins, to don their gowns and pose for a group portrait. Houses and trees can be seen in the background. At left are a flying swings amusement ride and a ticket booth.
