If there's definitely an MX safari I missed this Fall, it's the Motocross dei Campioni (Motocross of Champions) organized by Valention Rossi as a fundraier for kids leukemia, 30 years after his dad Graziano and friends organized theirs.
All of Vale's friends and more came, along which Marco Melandri, Marco Simoncelli, Kevin Schwantz, Andrea Dovizioso.
