No RV withdrawal, here! We live in east central Indiana, and just spent six out of the last ten weeks at three different parks. Indian Lak SP was the farthest north. Boating, bikes, hikes, some shopping. A few nice places to eat on the lake. Then south a bit to Millersburg, Ber'lin area. Great sights, nice campground, Berlin RV campground. Super nice people lots of cheese, antique store and do-dads. Beautiful country and the best kept farms anywhere.
Two weeks in the Hocking Hills SP is about enough to hike all the trails. Lots of caves, cliffs, and food at Grandma Faye's, just up the road.
Have fun the heartland and don't even think of giving up your RV!
