Skills.

Seriously. Warren has mad skills. This video was taken about 3 minutes after Andrew took his training wheels off.

Warren wouldn't let Andrew show him how to balance or ride it.... "Back off dad. I'll do it myself."

Now he is doing tricks and lifting his feet up in the air, standing while he's riding, making sharp and quick turns.

I'm afraid he's going to be one of those extreme sports guys and I can't do anything to stop it.
