Was there when my dad lost his leg (diabetes), it s a harsh thing to deal with but better to be above ground dealing with it than pushing up daisy's. Good artificial limbs these days, he might very well be back riding some day. Glad you were there for him, would have been that much worse hanging in that tree alone wondering if this is it, you did good. As for flaming the guy, ya never know, if ya have any serious time in the twisty's you know it only takes one microsecond lapse of focus and you are in trouble, 99% of the time we pull out okay but we all know there is that 1% chance that we wont, just, circumstance, and fate will determine what the result of the lapse is going to be. Safe riding everyone.
