For midwest/chicago area jeepers I found this. I would assume its mostly for crawlers but they say all jeeps are welcome. I have heard of the dealer Extreme Jeep of McHenry. But this was a dealer to bite the dust during chryslers dealer closings. They still will be around though as a used dealer and i guess they are still running the jeep event. Id probably check it out over that weekend. Ive seen it posted by other people on various other Jeep sites too.
