A Four-Wheeled Fascination chronicles the evolution of Roller Derby on a global and local scale. Since its creation by Leo Seltzer in the 1930s, the sport's rules and players have changed. From the original banked track to the current flat track leagues, roller derby has seen its fair share of struggles and success; transforming, resurging, and melding into its current state. Now played throughout the United States and with more than 450 flat track leagues worldwide, Roller Derby has reinvented itself once again.
