Took a little bit of recon to find this since Little Big Econ has so many trails. Clean but not very secluded area if a busy weekend, you'll have have lots of hikers-by.

First timer car/tent camping and our stay was perfect. Deer roam happily around and your wake up call in the morning is courtesy of feisty Sandhill Cranes calling back and forth. Park and facilities were super clean. Nearby trash facilities checked and cleaned multiple times a day during our stay. I can't say how crazy it is during the summer time, but in the early fall it's a beautiful campsite to just hang out in and chill.
