I'm going on a short road trip with my mom and sister during the last week of May. We'll be starting in St.Louis, and our destination is Washington DC. We're thinking about spending one night in Nashville: other than that we have no plans so far. We'll probably be on the road for three or four days before spending a few days in DC and NYC.
I'm from Norway, so I don't know much about routes, roads, cities, sights, etc. All good ideas and tips will be appreciated!
