"Happy Day Rides" was a traveling carnival with amusement rides that went from town to town in Colorado in/or before the 1930's and through the 1960's. Three of the adult rides were the Loop-O-Plane, the Ferris Wheel, and the Octopus. The owners were the Oxford family, but I can't find anything about what happened to this family and their business. Any update will be greatly appreciated. (Chase)
