It sounds very cliché, but the concept of the Sun Corridor Trail was honestly hatched on a bar room napkin! Steve Andersen with Pima County Natural Resources Parks and Recreation was receiving an award at the 2013 National Association of County Park and Recreation Professionals meeting in Houston, Texas. Steve was being recognized, in part, for his work on a loop trail around the City of Tucson called the Tribute Trail. After the meeting, R.J. Cardin, Director of Maricopa County Parks and Recreation, and Steve began discussing the similarities between the Maricopa Trail, a 315-mile loop around the great Phoenix metro area that was under construction, and the Tribute Trail that was getting underway. On the back of a napkin, the two began discussing the potential of linking the two loop trails using the Central Arizona National Recreation Trail (CAP Trail) in Pinal County. The CAP Trail seemed like a viable option since Pinal County was already in the planning and development process for this corridor. The two soon enlisted the support of Kent Taylor, Director of Pinal County Open Space and Trails, and the concept of linking three counties took shape.
In subsequent years, a small group of county and city park professionals had begun to meet to discuss linking communities along the route such as Marana and Casa Grande. The growing popularity of urban trail loops statewide was noted during those meetings. Flagstaff, for example, had one of the original urban loops, and the burgeoning Prescott region had also begun the development of a loop system.
