I think running the championship adds something. Imagine if the national series didn’t require the Grands?
If you take the locals out of the state series I think it kind of lets the wind out of the balloon. Theres not much incentive for racing hard. That same logic could be used to take locals out of the Regional series and then what are you left with?
They could change state plates to NJ1, NJ2 etc and allow you to run them wherever. I think it would be awfully confusing at the Pres Cup if you could run a state number as it is today!
