Don, the Ruritan's (fairground owners) will have their kitchen up and running with a simple breakfast (coffee, egg's, pancakes etc), lunch (burgers, chicken tenders fries, soda, etc.) that are pay as you go and a dinner on Friday night that you need to buy a ticket for in advance. After hours hanging around the camp fire is a BYOB and lawn chair event!
The fairgrounds has a rustic bathhouse with showers about 100 yards from the camp area with spot pots much closer.
Restaurants, Walmart, groceries, etc are only 3 miles away...truck stop with convenience store food & beer/wine is much closer.
