The Duvall Zone Picture a man on a motorcycle outside of Duvall. He is parked by a sign that leads into a forest, and stairs wide-eyed into the mist as pavement turns to gravel, as punishment beckons him to enter the woods, and howls of over-revved engines, shrieks of bending steeal, screams of mortal agaony, and the laughter of his riding buddies fills his ears. Yes, he is preparing to enterâ¦. The Duvall Zoneâ¦. On a Saturday morning, in the not too distant future, an undetermined number of Advriders may once again creep back into the woods east of Duvall. What awaits them, only a select few know â but it is punishment that awaits them, yes punishment; clutches will burn, tires will smoke, plastic will shatter, as the impossible ride will be attempted by the unknowing riders in the unforgiving ride. Would you return to The Duvall Zone? Would you risk bike, sanity, endless weekends of repairs and rehabilitationâ¦ to return? Donât adjust your dial, donât adjust your carbs, donât tell JoMamma where you are going, because, once again, you will enter, but may never leaveâ¦. The Duvall Zone. This show is rated R1200GS. Riders with Big Pigs may attempt this ride which will include steep hills, deep mud-pits, over-grown single track, and generally crappy terrain.
