One of the nation’s leading racing historians is making a stop in Jeffersonville. Indianapolis Motor Speedway historian Donald Davidson will host a discussion on the Indianapolis 500 and take questions Thursday night at the Jeffersonville Public Library. Davidson says there is a lot of interest in the Speedway in southern Indiana and says the most notable driver is Charlie Glotzbach, who spent most of his time on the NASCAR and ARCA circuit but also tried to qualify for the 500 two times.
