So, here's the update so far: the drive wasn't too bad. The first day was full of LOTS of "How many more minutes?" We tried to convince Carson that he needed to start thinking in HOURS. For some reason, he kept saying "Welcome to California!" But both days we were able to stop at a rest stop and have our picnic lunch. The first day we had gorgeous weather and we ran around and Trent even played some ball with the kids. It was a great break. We all look a little worse for wear since we got up at 3:30 am and got straight into the car!
Little port-a-potties? Genius! That stretch between Sacramento and the Grapevine is torture--not very many clean stops. :)
