I've camped here a few times, not a bad place depending on the season. Can get pretty busy, but not as busy as Bluestem down the road.
If you want to avoid camper cities and crowded camp sites within 30 minutes of Lincoln Nebraska, Olive Creek is a good choice. Primative, tent only, and far enough from major roads to reduce man made noises. Enjoy excellent star gazing away from city lights. Bring drinking water.
