I just saw on Midwest Racing Archives that Johnny Rutherford won $1,786 for winning the USAC Sprint feature at Terre Haute on June 13, 1965. That would be equal to $13,283 today. Per the article, the total purse then was $9,065 which is equal to $68,223 in 2015 dollars. I am assuming that this was a single day show as multi day events were almost unheard of back then. So my question is....Is there any single day, non wing event that pays anywhere close to this? If not, why not? Were promotors more willing to take risks back then? Or were they better at promoting to draw a crowd? Thoughts?
