Andrew wanted to learn more about my camera, so I explained how an SLR works. Then he wanted to take a photo of his camera with my camera. Ooh, and then he wanted to use my camera to take a photo of his camera displaying a photo. It all got a little too meta for me!
A couple weeks ago Andrew and I went to Cub-O at the Sid Richardson Scout Ranch. We spent the day learning orienteering with his den. I explained it to Andrew like geocaching without a GPS. The ranch had set several dozen flags out and our job was to find as many as we could within 2 hours. Our den did pretty well, finding 9 and hiking almost 2 hours.
