You're the man. That is freaking awesome that you are so involved with your kids lives, and doing something for them as most of us wish we all had when we were younger.
I remember I got a 1987 XR100R Honda Dirt Bike when I was 9 years old. I drove that bike to the fullest, and definitely had the most enjoyable time doing it! Before and after school everyday!
