More dangerous than motorcycling?

I did my first tri this weekend at Donner Lake and when I came back to the finish line, my boyfriend had tears in his eyes. Turns out, it was only half from pride. The other half was in assisting with a situation in which one of my fellow athletes nearly lost his life in the water. After my race, we went to the hospital to see if we could help the families in any way and we learned the guy was in ICU and hadn't woken up. My boyfriend is a motorcycle racer and now he understands why I freak out when the course is red flagged and I can't see him. It didn't one occur to him that what I was doing might be dangerous. http://www.kolotv.com/news/headlines/1705002.html
When I was in the water, I heard the airhorn and saw the Seadoo, but I had no idea there was a serious situation going on. I can't tell if I'm glad I didn't know, or I wish they would have done more to alert us.
