Where is the best place to camp before the Rally?
My choice would be any state Park. You will have to reserve now to get in some of the parks, as most have 100 per cent fill rate. My number one and two Eastern Wisconsin choices would be Harrington Beach and Andrea Kohler State Park as they are on Lake Michigan and will have the coolest sleeping at night.
I would also look for some of the County Park, like the Sheboygan Marsh Park, which is located two miles out of Elkhart Lake at the north end of the Kettle Moraine Scenic Drive.
Another place I would consider, would be Soldiers Grove City Park, as it has some of Wisconsin's best Riding Roads. The park could host the Rally, as it is huge.
