Sunken in-ground trampoline. Don't get me wrong, I love the idea, but... Now you have a big hole for all water to drain to and sit. I bet that will not only smell great, but attract a lot of bugs and Mosquitos. Yay!!
Road Trip Snack Boxes for Kids - I made these for this summer's trip and it was a huge hit. I found the boxes in the craft section at Wal-Mart and included a variety of salty and sweet treats. Then on each leg of our trip (divided up into 1-2 hour increments), they could choose one or two things to eat. Very convenient on us as parents and the kids love it, too.
