We wanted to camp Nebraska's national forest for some time and we were not disappointed. The camp was full to the brim.  all sites with hookups were taken, but the overflow is an abandoned, overgrown baseball field.  It was great, spacious, close to the showers and flush toilets, and only $8 a night!

I think hookups were only $16, so this is a great deal no matter how you slice it.

Neighboring Thedford has Kayaks and Tanks you can rent.  Tanking has become a Nebraska Thing.  fitting a group of folks and possibly a keg in a horse tank and floating down river!  We hiked to the ranger tower and it was a great hike with a spring fed trough half way up.  Much to see in the surrounding area including art galleries, quilt shops, and more.  Nice camping supply store right in Halsey.
