When are you coming through & do you want to pay for a site or just need a place to catch a quick snooze before moving on? If coming in winter, there are very few CG's open in that area.
Cedarbrook is a nice campground open all year, & I'd recommend that one. Their drive is narrow & would be quite difficult to maneuver if snow covered, but you can call ahead for conditions. You can check out my review
of it in the Campgrounds section. Other choices would be Olive Branch Campground
(exit 36) & Beechwood Acres
(exit 32 - I think). Call ahead first, to see if they're open in winter - they may not be. It's been at least 7 or 8 years since we've been to Olive Branch, but of what I remember, it's a small but neatly kept little campground.
There's a Flying J at Jeffersonville, exit 69. Also, WalMart Supercenters are located in Wilmington, OH (take exit 45) & Washington Courthouse, OH (take exit 65).
