I am planning a trip back home to the Buffalo area in NY from SW VA. Normally I would head up through PA but since I am going it alone (well, with just the kids), I have no inclination to drive anywhere near Pittsburgh...I hate it. So I am thinking of taking a 30 minute longer route that will bring me up on I-77 North into the Erie area. Any reason that I shouldn't? I have driven 71 before when I traveled from NY to Nashville frequently and found it to be flat and easy to drive. Hoping 77 is the same?
