The Indianapolis Motor Speedway itself is putting out the call to all unique and unusual rides from the 70s. Owners are encouraged to roll in and help celebrate the 91st running of the Indianapolis 500 at the Psychedelic 70s Car Show, from May 18th to 20th. As a Sunday bonus the entire group will be invited out onto the Brickyard for a parade lap. Brush the dust off that 1976 Mercury Bobcat, break out the 8-Tracks, and register before May 11th.
