SEVEN-year-old Camden Butler's trophy case is bulging after he cleaned up at the Wellington motocross championships at Foxton last weekend. The Masterton schoolboy swept all before him in the 7 - 8 years 65cc championship, winning all four races. Camden, who can't move up a grade until he's 9, is struggling tofind competition in the lower North Island, his mum, Rachel Carson, said yesterday. He's been racing in Taupo, where the competition is keener, once a month and now lies second in that series. Camden's dad, Simon Butler, is also an accomplished rider but has put his career on hold while he trains Camden. Camden is pictured with his trophy. The hat he's wearing is a prized possession. It's signed by Ben Townley, Darryl Hurley, Shayne and Darryl King, his uncle, Corey Sargent, and two newly-retired world champions, Joel Smets and Stefan Everts.
