The single most significant thing I learned when on road trips, especially in smaller places, is when you get there don't look for the touristy things. Stop st a local diner or burger joint and ask the waitress what to see or do. Always get the most authentic experiences that way. I've had so many maps scribbled on the back of paper placemats or cocktail napkins. You'll find yourselves invited to all sorts of things that way too. That's the real american adventure
