Long car rides

So we are almost home from our 2nd trip to Philly in 3 weeks. I've come to the realization that I don't know how as a child I survived long car trips. First, I think I have an adult onset of ADD. Sitting in the car for 11 hours is dreadful for me. After about hour 2 I feel myself starting to wonder if ill get through the rest of the trip. But thankfully I have my kids to help with that since I have to turn around to start movies, pick up toys, and get food/drinks out. I will say that the boys are GREAT travelers-thank god for their portable DVD player and their 'guys'. :) thankfully we are almost home and we won't be taking another long trip til March...to Philly! :)
