"Pit Pass" Into Brickyard History - May 1910

Good summary of practice and preparation for the May 1910 race meet at the Indianapolis Motor Speedway. This includes impressions from drivers such as Ray Harroun and Bob Burman. There is a program of events, and even a feature that could be aptly described as a "pit pass" summary of brief items of interest to race fans. These articles were published May 25, 1910.
 
Note, too, that a brief item in this collection describes "large plank mountains" in reference to the wood ramps that were part of the obstacle course created as one of the special events on the program.
