The Mackinaw River winds through the northern landscape of McLean County, defining the rural character of this central Illinois terrain. The settlement of Merna serves as a local anchor, accompanied by the smaller hamlet of Fletcher to the east. Agriculture and transportation dominate the map, with the iconic path of Historic Hwy 66 cutting diagonally across the northwest corner alongside Co Hwy-65. This corridor represents the evolution of American travel, preserved here among a grid of county roads that connect remote farmsteads and small private landing strips like P.J. Killian Airport and Schlosser Airport.
