Mid America Motorworks will be hosting an autocross May 3rd on its corporate campus. It says low speed(probably for insurance reasons), but it there is one particular section where my Boxster S is doing around 60 mph so it's pretty fun. Check it out just to watch or participate, hopefully.
Here are the links. If you have any questions, just ask me.
