The first leg of our trip was a drive of about 7 hours - we left home around 2:45 PM.
The time consisted mostly of eating, reading, and listening to a book on tape, "The Time Machine" by H.G. Wells. I wondered if it might be a bit frightening for the children but took heart in the fact that we'd all be sharing a room that night so the Morlocks would probably stay away from the kids :)
The hub pointed out that falling asleep in the car was a bit like "time travel"...(it would definitely be time travel if you were the driver that fell asleep)...
Nowadays the hub or I are more likely to nap in the car than the kids are. They both took only one nap throughout the many, many hours of riding in the car.
We ate supper in the car and I found a new good travel food - summer sausage. Everyone likes it (if we forget about how unhealthy it is), and it doesn't need to be refrigerated until opened (if you buy a small package it can easily be consumed in one sitting). We try to avoid bringing a large cooler with us b/c we don't have the space in our car - usually one of those small soft-sided coolers is all we bring.
