The feeder for the Gold Cup now is clubs. 5 years ago, travel was less expensive, and 10 years ago it was even less. That allowed budget racers to make multiple 3 or 4 day weekend events more than once a year. Now, racers can barely afford to follow the entire 4-race schedule that is the Gold Cup program.
IMO, the best way to promote 4-cycle racing is at the club level. Regional racing is not what it used to be, and while its sad to see, it’s just how things evolved. Until the numbers of 20 racers in a class at the club level exist in the Great Lakes area, I don’t see the need for another traveling series.
