Packing Suggestions?

OK folks: confession time. Neither of us has done a road trip before, so we'll need recommendations!

We're already packing:
At least one GPS (two if you count the 'droid, which I kind of don't), with related accoutrement
Chargers for all our electronic devices
mp3 players packed with music we love and maybe the occasional podcast (podcast recommendations?)
A cooler for on-road snackies and drinks
A very nifty converter thingo that plugs into the cigarette lighter to turn it into 2 cigarette lighter ports and 2 USB plugs

... does anyone use paper maps anymore? ;-)

Other than the obvious necessities for a 2-week trip, what have YOU found necessary/nice to have when travelling by car?

Vacation!!

This is the place you want to be if you want to read about Kate and Misty's Big Adventure: MA to NOLA to FL and back, and quite a lot of stuff in between.

We're leaving on our road trip on March 4th. It's a road trip in a car, since getting out of Massachusetts on motorcycles in early March is a crapshoot at best, not to mention getting back into Massachusetts in mid-March. We'd toyed with the idea of trailering, but really, the amount of partying we're planning on doing wouldn't lend itself to much riding, and in a car we can carry a LOT more stuff AND swap out driving duties.

So far we have hotel reservations for three nights in Jacksonville, FL and two nights in Savannah, GA. We'll have a Subaru Impreza, a laptop, a Droid phone, a camera, and our moto gear (you never know!). Everything else is going to be come-as-it-may. See those wings on the seats of our pants? :-D
