Nathan's Dream Sport

We just discovered a sport that's been around since the early 1900s. It's called Parkour. Nathan already does this - though on a much lower level. When I first saw some YouTube videos of it, it reminded me of how Nathan has to jump off of every curb, swing on the shopping cart stalls in the parking lot, walk along small walls, and generally be just non stopping! Maybe someday he'll be jumping off of buildings! Yikes!!
