Scooting, that is funny about the tree. I guarantee if my brothers and I had any power wheel anything when we were my kids' age, everyting would be in danger! Heck, we had go karts when I was 12 and my youngest brother was 4. That little turd ran in to the back of my bicycle and knocked it clean out from under me. And that was with the "Vice Grip" govorner our dad rigged up on it.
