I've learnt something today....

...when putting a fender on a full suspension bike, don't forget to
"adjust" the hight of the fender to the rear suspension sag...


...or, don't go out for a two hour ride with your IPod so loud that you can't hear anything else but your tunes, cranking away on the big chain-ring and think that all that grinding noise is due to all the yak on the Keystone!?!
But then again don't they teach us to never look back:)
Anyway, I had a good laugh when I came home and finally realized (doooh) what happened.
