a_d_a_m Thanks.
At the very least, next time I'm through there I can keep my eyes open. It could be what I interpreted as tent pads might not be tent pads, either.
A few years ago when I went down through there I took a mental note of a nice trail-side shelter and did a day trip down that way with my girlfriend with the intent of picnicking at the shelter. Come to find out I was a whole town off - we never did make it there so we hit another spot. When I did my OTET trip last Fall I stopped at the nice shelter for lunch, though (and to get some sun to charge batteries). Now I know where that is - about 1mi W of Florence (Neil Rd crossing). That isn't a "camp spot" though, nor is it close to Xenia like I am imagining.
