1911 Indianapolis 500
Throughout the remainder of the season, however, the crowds grew progressively smaller, and after seeing a second decline in attendance in as many days for Labor Day, 5 September 1910, the final day of the concluding meet, Speedway co-founders Carl Fisher, James Allison, Arthur Newby and Frank Wheeler conferred to decide on a new course for the following year. While the appearance on Monday of some 18,000 was reasonable enough, given both the rain showers occurring early that morning and the large parade held downtown during the afternoon, neither the two days of the Labor Day meet nor the July 4 weekend races had come near to equaling the Memorial
Day turnout. While potential explanations for the decline included the high heat of summer and the women of the city making family holiday plans that did not include automobile racing, one of the most likely, they reasoned, was an overabundance of the very events they exhibited: too many races had diluted turnout to including only those most interested in the sport.
