Always something worth seeing!
I always laugh when someone asks "is there anything worth seeing" (no offense intended). It's all in your perspective, I guess.
There is a lot of information available to you for planning a trip to little known places -- with a lot of it right here at RTA. Check out the books section, and the RoadTrip Planning section. Chris Epting's books would be of particular value to you for what you are seeking.
From your first post, it is a little difficult for me to visualize what your route is going to be -- the places you mention don't leap out at me as being connected -- if you'll give us (or maybe just ME) a bit more information on how you plan to get around, route-wise, perhaps I (and maybe some others as well) can offer some additional suggestions.
