Closest we have here is Wisconsin International Raceway over in Kaukauna. It's 100 miles away though
There is one in the western part of the state, I think it's called Rock Falls Raceway or something like that. Also 100+ miles away. Only other one I'm aware of is Union Grove down in the Milwaukee area somewhere but it's at least 200 miles away.
I vaguely remember being at the "Last Drag Race" at Lions dragstrip back in '72(?) That was a year or two before we GTFO of California. I was only about 8 years old at the time but do remember we left about 1/2 way through because it was getting way out of hand. Lions was shut down by corrupt local government basically. They cited noise complaints as the reason they were revoking the lease agreement with the track but that turned out to be total b.s.
