Playing outside in Ohio

Can you guess which child came up with this game? Sir Charles is braver than the rest. Right after I took this video he decided to JUMP from log to log. I warned him and tried to stop him but it wasn't until he toppled in slow motion backwards to the ground that he decided to play with the frisbee instead. Boys will be boys right? Actually while we were at the playground, Charles was tossing rocks in the air. I was asking him to stop and go play on the swings. A man who was there with his two boys that were probably 8 and 10 years old said, "You can't stop them. It's built into them." I had to agree.
