Before they fixed the chassis design, traumatic leg injuries were very common in Indianapolis racing crashes. The best guys to who developed the medical response to those are still around, Terry Trammel and Steve Olvey and Kevin Scheid.
Man, I still feel bad about Alex Zanardi. Back when I cared about that sort of stuff, the Target team (Scott & Alex) were my favorites. The bit where he cut across the grass to win that one race was ... amazing.
As for Mr. Woods, well, I’m not a golf fan, but I hope that he recovers enough to enjoy life and at least get in a round or two with Donald. :)
