The staff and management of Mercer Raceway Park mourn the recent deaths of Art McDonald and Dow Carnahan. McDonald was a mainstay in the Modified division for many years. Carnahan was one of the region’s best known voices, with experience as the track announcer at three prominent area speedways and as a special events announcer for the prestigious Dirt Track World Championship.  They will both be missed by families, friends, and the entire racing community.
