Scheduling can be a challenging thing to navigate with this many tracks to race at, I am planning a track owners meeting sometime in June. I am waiting until Bill Bostic gets home. I will send out an email or text as soon as I can after I talk to Bill. It will be all 4 of us track owners to prevent scheduling races at the same time. I know you don't care about the OSCAR races, but those can impact the schedule too. Bob Hanna is has scheduled a special OSCAR race on September 27th at Sparetime Raceway in Roseburg. Looking forward to getting together and getting the schedule worked out.
