Probably right around then.

Before that though,it was called Mid America Speedway,and they ran motorcycles there but not every week from memory. I went there a couple times for something to do after the regular season in Indiana ended. They'd have a race around Halloween,and thats the one I went to.

I didnt add it to my speedways visited list till last year though when I went to the USAC sprint race late in the season.
