Monkeying around

Last week after school, we stayed at B's playground and played with some friends. I turned around and saw J going for the monkey bars. What is really amazing, he is on the second bar. No, I did not put him there and by the look on his face, you can tell he is amazed he made it there. He also did not hesitate to drop when he was ready. The bars were probably 6 feet off the ground. He seems to have no depth perception, or he just does not care. Yesterday we were at the park and I turned around to see him jump off something that was over 4 feet off the ground. I don't know how his little bones can handle the repeated jumping!!!
