You might want to consider going to the Alumapalooza and combining it with your trip. Jackson Center and Airstream Life Magazine and others are having a big Alumapalooza from June 1-6th. It will be set up with lots of activities, seminars, tours, and the JC street fair. Maybe some of you havae missed the thread and discussion.

Ohio State Parks do have reservation lines and you can reserve online as well. They do not take reservations during the winter months. You are on your own to find one that is open in winter. Ohio State Parks - Campgrounds
I can recommend Grand Lake St. Mary State Park which is not too far nw of Jackson Center. A beautiful place to camp with nice facilities and right on the water.
Good luck on your planning.
