Here's a picture of the kids at the entrance while we were waiting for Aaron and Papa to park the cars.
The older four posing in front of a WWI era plane (I think!).
Aaron's Grandpa was a POW in WWII. Here Caleb is finding the location of his Prison Camp on the map.
Caleb sitting in one of the cockpots. At this point - my batteries died on my camera, so this was all the pictures I got.
