I say keep the open practices. I don't care if its across the street from a scheduled race. Just give the RACERS more bang for the buck. And the simple answer to that is more seat time. Like it or not, the only way to that goal is a reduction in classes. A 7 min moto is killing racing. Anyone that understands simple math can figure out it is not worth it to race if that's all the time you are going to get.
Been saying it for YEARS. And it only takes one track to say I am going to try it.
Max 14 classes.
minimum of 12 min moto's.
If the numbers don't go up after a year, then go back to your 7 min races. Trying it will at least shut me up, and that has to worth something.
But really, it does not look like a big ask to have only races on Sunday. You can have the other 6 days to open for practice. Just leave Sunday alone...
Oh, unless you have lights and want to race on a Friday or Saturday night. But then you don't have to worry about other tracks being open for practice.
And practice is a hobby. Racing is a sport.
