This summer my brother and I are planning a trip from near Reading, PA to the middle of nowhere near Nashville, TN. Is there a recommended route or routes?
I've been using Google to help figure out routes, but they don't explain why they take me certain directions....

Here is the rather round-about route that shows up when I ask for bicycling directions from Reading to Nashville...

I was also considering this route:
http://maps.google.com/maps?f=d&sour...18&ie=UTF8&z=6 ...but even though it is more direct, it goes through all those mountains....
I don't have any maps yet...and don't know what ones would be best for this route...
