MTB toured in the Poconos and eastern PA hills a few times. Rear rack and a day pack. This was before I knew that such things as "panniers" existed. Bag and tent on the rack, everything else (which isn't a lot) in your pack. I 'spect you could use some rear panniers, but for three or four days (which was as long as I stayed out), you'd be allright with the rack'n pack. Plus, it keeps things light. You'd be surprised at how much you don't need.
