Probably one of the first tracks running 600cc and then 1000cc midgets would be Little Salem also known as Thundervalley speedway in Salem Indiana.
This is the track we started racing on many years ago and I think It is still the best track for 1000cc midget racing period. It is small enough, banked enough and wide enough to allow these cars to really perform at their peak.
They run a weekly show for the 1000cc midgets and also sanction in some traveling groups.
