I ran a DE at Gingerman with the Northshore Corvette Club last year. I am sure they are doing it again this year. Very nice group of people and very laid back. They are the only Corvette club I have found around Chicago that actually goes to a track. Why are so many Corvette folks into buffing and polishing only, the Z06 is close to being dominate on the track have some fun! There is no way you can enjoy all the perfomance of your Z on the street. I have to run with PCA groups to get the track time I want, most are very accomadating to other makes of cars.
