Who We Are

It may have been the “Summer of Love” for the rest of the U.S.A., but in rural western Oklahoma, four young ministers were eking out a living from the low wages of the 1960’s. When Clayton Callahan built himself a steel carport, it attracted considerable attention from the country folk, and soon a neighbor was clamoring to have one. The first carport was sold. Clayton along with his youngest brother Neil Callahan and their two best friends, decided to see if a living could be made selling carports.
