...Southern Illinois Raceway in Marion is having their season finale. Winged 600cc micro sprints, non-wing micros, 4-cyl hornets, plus the 100cc junior sprints for the little guys are on the card. One would have to imagine quite a few POWRi micro sprint regulars will be on hand.
As an additional enticement, general admission is just $5.
