Great video. My nephews are racing in Wichita, Ks today.
My sisters boyfriend got my nephews into bmx. He (42 yrs/old) broke two fingers and collar bone last year. He hasn't broken any bones this year. Oldest nephew (12) landed flat on his back from about 5 feet in the air. He's a Donaldson, and didn't cry. I'll stick to my slow place on my mountain bike.
