I hope we can all get over this. I learned as a very green racer years ago at the same track( very different owner then) I and a buddy were in the just into the money rounds and track owner let several loosers buy back in, this was after 5 rounds so you can imagine the car count was good for the track profit anyway. That track has been great for melast few years!
In short, buy backs purchased after the loosing round by the looser, or loosers buy into a 1st, 2nd, or what ever round gambler's race is what I like, and the track net will be higher and the racers get more rounds. But what ever the track or club need to have the rules well understood.

There, I'm going back to work on my car. See ya at the track.
