"Merry Christmas!" It sounds through my car window as I pull into my parking spot at the second round of the Maxxis British Motocross Championship in Kent this past weekend. As much as that was meant to be a joke, you could swear that it is December 25 because the whole track is thinly covered in the white stuff, with the heavens opening up to chuck some more of it down. But no, it's Easter Sunday, it is March 23, and white Christmas is three months late.
