Decent campground, tent campers are right next to RVs so you get the random RV light on at night.
Stargazing is acceptable to the north, but don't waste you time looking anywhere south. Springfield lights drown it out.
They are right next to a boat launch on the Sangamon River so that's a plus. Right next to the boat launch for a car. I wouldn't want to haul a kayak or canoe to the 1 mile to the campsite if I could avoid it.
The lady I had for check-in was super sweet and friendly so that's a plus. Check-out is just drive away. No phone call or anything nessesary.
Firepit was overgrown with grass and the stone ring was broken but that was an easy fix. Plus they do let you bring in your own firewood so that's always nice.
Overall I'd say average campground. They have some nice parts, and some meh parts. While I wouldn't go out of my way to avoid them in the future, neither would I go out of my way to revisit them.
