We pull are covered wagon every year down to Thurmont, MD for one of our Sass events and as Caissiel said get yourself up to 84 in Pa and go by the rest of their directions. This is also the non toll route until ya get to 90 in Ma. Plenty of fuel stops along the way, we stop at the bigger truck stops, if you don't have the book Next Exit get one, that will tell you whats off every exit.
