In his last trip to Bulloch County, Jack Fussell jogged with purpose. The 62-year-old Canton, Ga., native, clad in bright yellow and pushing a stroller filled with water and goods, passed through Statesboro as part of a more-than 3,500-mile trek across the United States to raise money and awareness for the Alzheimer’s Association. The coast-to-coast adventure that began in January has ended, but the mission continues.
