There's nothing unusual about crowds at race meetings being larger on a Sunday than a Saturday. That's the way it's been forever. But there is something unusual about that crowd building into and during Saturday evening, well after qualifying is done and dusted.
And there's nothing unusual about said crowds invading the track after a race, to get as close to the podium as possible. But, again, there is something unusual about the mob booing two thirds of the competitors on the podium.
These are all things that happened last weekend at Mugello, largely as a by-product of the popularity of one man: Valentino Rossi.
