Elmer Lock sits behind the wheel of his midget racer in this photograph from June, 1936. In the 1930's, midget racers like this competed regularly under the arc lights of the Tacoma Speedway Royale at South 14th and Sprague. The races varied in length from 3 laps for a "helmet dash" to 30 for a class A "Main Event". (T. Times 06-01-1936 p.11)
Another great photo from the Tacoma Public Library's South Sound Photo Album.
