I am planning a trip around the South. Soon, I will have visited every state in the continental U.S. Arkansas is one of the last ones I have to visit. I've been researching it a bit, but I haven't yet found anything there I'm really excited to see (especially not that I'm wanting to take time away from other parts of the trip for). However, I'd like to see some part of it while I'm in the area. What would you recommend for a short visit in the eastern part of the state? My top choice would probably be a place with pretty/unique natural scenery, but a particularly noteworthy historical place would be good too.
Also, if you wanted to visit a place with traditional southern architecture (plantation homes, etc), which towns would be your top choices (not Arkansas, other places in the South)?
