Hope this is better. The red arrow is the entry to the campground mentioned above (too tired to type that name in here
The diagonal street is Waupun. The north south street is Knapp ( a major thoroughfare during OSH). The food court has a pretty good variety of food. There is usually a BBQ guy also in that immediate area. When you pull off the street into the campground (red arrow) there is a little kiosk to check in. I have parked here before and they do charge for parking. Just sayin'....
Most of all have fun.
