Nope, no ROC Race. I guess it could be due to the drags....
As to why not other nights, I would say it has to do more with the racers than the fans. If you live more than an hour from the track, it would be VERY difficult to make it for an evening race. That includes Friday's too. I raced Chemung Last week Friday, and I had to leave work at 2 in the afternoon. ( I have a 2+ hour drive) That is bad enough, but if that was any day other than Friday, you also have to deal with getting home at midnight and making it to work in the morning.
If you are close to the track all of that is not a problem, but I think you would see a decrease in cars.
The biggest issue is that tracks need to synchronize schedules. Instead it seems a lot of times they try to compete with each other, instead of working with each other.
Anyway, back to my original post, Sundays, at least to me, are difficult. I, Like a lot of people go to church. I also think Sunday is "family day" for many, and this time of year, with graduation parties and such, it seems like Sundays would make for lower crowds.
But, what do i know, I am just a racer
