The Armstrong Family has been harness racing at Exhibition Park Raceway for more than 100 years, but the future of the horse racing family may be in jeopardy. The once-thriving business has taken a serious economic hit in the last five years, and is now the last of five tracks in the region. Luke Armstrong, 21, hopes to turn things around and encourage young people to get into the sport by leading by example, racing alongside his father in a tradition that has lasted five generations.
