The trip from Providence to Maine takes 6-7 hours, so we usually stop at least once to let Libby and us stretch our legs. Freeport is the perfect place - it's about halfway through the trip and they have outlet malls. Need I say more?
We picked up a large cheese pizza and ate it in the car. There were eight pieces of pizza... Shannon and I each ate 2 pieces while our little darling Libby had FOUR (though she didn't eat all of the crusts). She's a growing girl!
