Yes really. One of my entrepreneur friends is renting out the entire track and he asked if I knew anyone that would want to come. Here is the sign up if you want to come since I would love to see a freaking fleet of bimmers amongst the Italian cars. He's the president of ChicagoRally.

Here is some inspiration (this is last week at the Autobahn CC at an open track day with team stradale). =) The guy goes all out so I wouldn't be surprised if there are multiple photographers at his private event as well as instructors for free lessons on driving the right line, turning apex, etc.
