Get the tracks behind it first, as you need to get the events either scheduled on the same weekend as club races, or off club races and other events members may go to. I think a GoPro Motorplex, Carolina Motorsports Park, and one of the Georgia tracks would be a great regional series.
GSKA out of Lamar County Speedway in Barnesville GA is always up for anything that will draw more karters. We have a pretty good LO206 group and it is growing. We have some of the best group of people out there.
