It might be the timing
We had a wooded site in the Sunset campground, mid-week.
The sites are rustic but nicely groomed with a tree line between most campsites, although almost none of the spots had occupants. The camp hosts were very nice and very communicative about all the happenings. Picnic table and fire pit included. Long enough drive in for RVs. But enough grass for tenting. Not many trees available for clothes lines.
Unfortunately, we might have had bad timing. The beach was closed due to high levels of bacteria. The pit toilets closest to us were also closed due to a bee hive being found so we ended up driving to the flush toilets if there was any urgency but could walk if you wanted. We also picked a spot by the water fountain. The water was yellow from iron. It had just stormed so the bugs were bad and everything was wet. So mostly a series of unfortunate events but we still enjoyed our time.
Because this is a prairie, there is so much to look at! The hiking trails are great through prairie and woods. The sunrise over the prairie and the sunset colors of the sky were great.
