The largest custom bike and car show in the Midwest, the Donnie Smith Show – Midwest Extravaganza, Bike, Car & Tattoo Expo, is bringing authentic Indoor Flat Track motorcycle racing back to the Twin Cities, where the roots of the sport were born. For 13 seasons, from 1968 to 1980, the revered Minneapolis Armory hosted “The Indoors,” indoor flat track racing that filled otherwise dreary winter months with handle-bar-to-handle bar, down-and-dirty, bar-banging action. Over those years, hundreds of privateer racers found a home in which to compete. As one of the largest, most successful and longest-running flat track events, The Indoors put the sport on the map. Now the Twin Cities will welcome the heart-pounding thunder of flat track racing once again on March 23, 2018 at the Lee & Rose Warner Coliseum on the Minnesota State Fairgrounds.
