You need to be at Haubstadt. There will be some good cars and drivers at Plymouth, but not near as many as at Tri State having USAC. At Haubstadt there will be all the USAC guys plus all the MSCS (Midwest Sprint Car Series) there as its turned into a pretty big rivalry. Plus you"re closer to the other two tracks .Bloomington, Paragon. I really liked Plymouth the couple of times I"ve been there, but it does get dusty, where you don"t have dust at Tri State.
