the sis and i are headed down for a wedding and are making it a 3-day roadtrip. any suggestions for places to stop? the route has not yet been defined -- and i was hoping to do that based on what kind of eats there are (say, in arkansas vs. indiana). we're definitely stopping in nashville for hot chicken, but our primary objective is BBQ, and lots of it. we're big fans of local food, specialties that are particular to a place, and establishments that speak of a particular area.
what say you, chowhounds?
