I'd like to speak up on behalf of granite which is not in a position to defend itself:
It is maligned left right and centre as being the medium that clogs up IMC:
If you look at most of the recent accident in poor weather reports: the granite that is glibly talked about has in fact often been soft mud, often overlain by meadow grass.
So: leave granite alone folks, its not nearly as harmful as you'd think in the right hands.
