Spectacular crash, and the GoPro footage just puts you right there. I expected a lot worse outcome, you are one lucky man. My buddy and I were wondering why you didn't lay it down or toss the bike when it started getting away, but I guess it's easy to arm chair the incident. Glad you came out OK and holy cow those DRs are built like tanks! Must be all that heavy steel in them, I remember having one of those for a few weeks and I got rid of it because it felt way too heavy for its size.
Looking forward to meeting you at Mendo, be safe.
