Stumbled on this genuine looking footage of the 1929 Kentucky Derby won by this week's noteworthy #20, Clyde Van Dusen.
Note the walk up start, sans starting gate.
Tough for me to follow the action in the mud and grain, but I'm thinking Clyde didn't do his "walking up" on the outside. Maybe someone can see it differently, but I never catch the outside horse making the lead....
