It's probably not a "proper" pose, but it intrigues me. There's something about little kids and their fascination with anything up high: trees, planes, clouds. They look up all the time! Call me weird but I love it. I probably have three dozen photos just like these.
It's okay, I know I'm weird. Now when you see me worming around on the ground with a camera, at least you'll know why I'm down there!
