Some years ago, a sign stood on S. Second St. in Chambersburg,  just south of Garfield which stated:  20 feet west of this marker was a half-mile race rack on which Speedy Slim ran a record of 1 minute, 21 seconds.  Evidently Fairground Ave. was named for such a reason – that’s where the fairgrounds were in the 1870’s and horse racing was part of it .  The fair was held there through the 1880’s.
