My Dad's got some nice bikes. I may just have inherited the bug from him. He's got an old Holdsworth that is pretty cool, but he doesn't really get the fixy thing.
Oh yeah, and he hasn't been able to outride me since I was 13 and grew legs

.
My daughter is 11 has a decent MTB, and is becoming a fairly skilled rider. Maybe someday she might even get into fixed. For now she digs gears.
My 7 year old son has Muscular Dystrophy, and rides in a trailer sometimes and drives a powerchair. Dr. Mojo, you're an inspiration to me. I doubt I could mount anything of the scale you are doing, but I might just look into ways to raise $ for Muscular Dystrophy research on my bike.
