SUE BROOKS and sister PATSY LOVE (left) are pondering the visitor's center at American Electric Power's Miners' Memorial Park in Morgan County, OH.    The main attraction at this roadside park is the bucket from Big Muskie the world's largest drag line that operated nearby until 1991.  The machine was electric powered and used enough voltage to power 27,500 homes.  Stop by Saturday and Fogeyisms will tell you more.
