Travel Games

We will be taking our summer vacation trip to Florida in a couple of weeks. In prepration for this trip I am trying to come up with some car games and activities. Since we are going to be in the car for over 8 hours on the first leg and then an additional 5-6 hours for the second I don't think just the T.V. will keep them happy. We are packing breakfast and lunch for the road and then will eat dinner when we stop for the night in Prattville, AL. If anyone has any suggestions of car games or activities to do in the car I would really appreciate them. The kids are really good travellers but it would be nice to be prepared.
