We stayed here one night after finding this through Passport America. Rate was super cheap - $15.50 per night. The only downside was being overrun with flies while outside.
Was here June 2012. Small gravel but level sites. A few pull thrus with poor asphalt paving and no sewer. Super nice and helpful owner. Many new upgrades to sites trees, grass and gravel. Owner owned washer and dryer that was available to us free. I would stop again just due to the owner being so helpful and nice.
Passport America rate very inexpensive. Pull thru's are water and electric only. Near dairy farms.
