Hi, John. It's likely that a return route would consist almost entirely of country roads, most of which have speed limits of 55 mph (and drivers often exceeding that). If you're willing to endure that, you could string together a few historical markers, museums, sites, etc. Of course, part of your return journey could consist of Amtrak segments, too.
