We are planning on driving from Philadelphia,PA to Baton Rouge,LA (to visit friends) and drive back. We want to stay 2-3 nights on the road each way. Shortest route seems to be 81-20-59 but we don't mind taking a longer route for interesting places. I know it is not the best time of year for road trips in this area, but any suggestions on routes? places to see? places to stay? I am open to almost anything at this point.
