Wow, I thought it was pretty young too when I saw how high that kid was goin, cruisin right along!
It's a good tree for it though... hehe, if they fell, they wouldn't pick up too much speed on the way down.
When I was like 12 I was way up in a pine above our old house when an earthquake hit. We lived 100 feet from the San Andreas fault line. Was quite a ride. Mom was pretty freaked out.
If it was my kid I'd end up giving em tips probably, then go find him a harness.
