Well I'm talking out of turn a bit as I didn't ride last weekend but from what I've been told they have dug out and put berms outside the of the neg camber turns up the top of the hill.
I just think that it was one of the best tracks I have ever been on, though I've only ridden a few, because it had a bit of everything including those neg camber turns, which made riders have a bit of a think plus it slowed the field down which made for better racing. The surface was near to perfect loam and the terrain and lay-out more than suitable for both riders and spectators.
AND one of the best for passengers TOO......
Think about being a passenger over an appearing horizon into a neg camber right hand-er, then having to jump over for a down hill neg camber left hand-er, which tightens up and runs along a neg camber terrace, which then kicks left and then dips down to the right.
(lucky I was on with Lama and not Hansi or even Popeye for that matter
