Freeze-It on the road

We just returned from a family road trip to and from Richmond, VA (about 7 hours each way). The day before we left, I was preparing for the trip, getting out the car toy box, packing snacks, and freezing foods. Yes, freezing foods. It is a great way to pack refrigerated stuff without having to haul a cooler with ice. When we travel long distances or go camping, I freeze everything I can think of. Juice boxes are a given. But I also freeze Gogurt, string cheese, hotdogs, sliced oranges, grapes, almost any kids snack can be frozen. I also pack some un-frozen versions in case someone wants a snack right up front. But some kids will think frozen Go-Gurts are a "road trip treat." I know mine do.
