Would it be worth to a team to purchased an annual $2500 charter each year for a guaranteed one of 15 possible guaranteed starting spots? Features could still be limited to 20 cars, but if you didn't have a charter you'd only be guaranteed a start if just 20 cars showed.
Now you want tracks to hit up what few cars local that are still around in any class, for $2500 so they have a spot in a feature? At what tracks are fields in any class, (other than maybe the Lernerville Sportsman, which may change this year), have more than full fields on a regular basis?
