Stayed here June 2018. It is a gravel lot. It had been dragged perfectly smooth. The grounds were very neat and clean. There was water and a dump station. Electric is at each of the poles in the lot. There were a lot of trains but once we turned the air on you couldn't hear them. There were grassy areas to walk the dog. We payed $15 in the after hours box at the office.
We paid $15 the following day. We woke up late. The fairgrounds opens at 8am, we came very close to being parked in. Electric on the wood light poles. Inexpensive over night stay. There was a K9 unit that patrolled the lot also.
All fairgrds the same. Stay cheap. 50amp no water/sewer. Some semi traffic, suspect local. Mostly quiet/secluded 4 us. We like. Put check N dropbox @ office.
