Solid campground
Very spacious campground that, according to the ranger, has filled to capacity maybe three times in the last decade. I got in during the evening and found a great spot up from the road on a small hill. I imagine it would’ve been hot during the day because there was no shade there, but good for just one night I figured. Unfortunately, a t-storm rolled through around 2am (my fault for not checking the weather before - no service here - nor did I check the bulletin board for weather) and I figured it was best to move my tent to the wooded area. Not fun to do in the middle of the night but at least I staked it back in about ten seconds before the storm reached me (next 1.5 hours was rough though).
The wind cave itself was closed for exploring while I was there which was too bad. A knock on the park, though, not the campsite. Was right around the corner from the visitor center/cave entrance otherwise which is convenient.
