I'm very sorry for the loss. It sucks to lose anyone and it's worse when it's a kid.
It's even worse when the lamestream media starts a E36 M3storm in the name of 'protecting the children'. True story: in the Northeast, a dirt bike club bought something like 250 acres so they and their kids would always have a place to ride. The sheriff (a woman) threatened that, if a kid were injured riding on that piece of property, she'd prosecute for child abuse. Cooler and more intelligent heads prevailed.
I started racing motocross at age 10. My brothers rode trailbikes with me, but I was the only one who wanted to really push it further. My dad never pushed me to do it, but he never told me I couldn't, either; in fact he drove the van and carried my young dumb ass out there every weekend. At the time, I felt I was indestructible, made of rubber and springs and I'm sure that worried the hell out of my mom.
That part of my life meant a lot to me as a kid and as an adult as well. Right up till he died, my dad and I could talk motorcycles, cars, hot rods, racing etc because we both 'got it', we always 'clicked' when it came to that and I'd never trade that for anything.
Fast forward to becoming a dad: my daughter does not show any real inclination to get into any of what are poorly named 'extreme sports'. But if she had, I would not have tried to stop her. Like my dad, I would have helped.
For myself, I wound down my motorcycle racing after she was born because as someone else in this thread has noted, I was racing against kids who didn't have mortgages and kids to worry about. I moved into 'safer' venues like autocross and hillclimbs, at least I have a cage around me unlike dirt biking.
I think that kids doing outdoor sports trump those who live vicariously pushing buttons on a game controller, even if it is more dangerous physically. At least the outdoors kids are living a real life, not some ersatz bullE36 M3.
