The North Shore largely went legit.
There was much hoo-haa with landowners, its all on private land, the forests are not public like much of UK
All the really mad really dangerous stuff has gone.
Each trail is now crafted by volunteers in negotiation with the landowners.
There is still lots and lots of incredibly challenging stuff, its very steep and very tech, with lots of wooden skinnys, teeter totters etc if you like them. Just not 40ft in the air.
Its really an amazing place, well worth a visit and get guided round if you ever get the opportunity.
Cove Bikes the shop is there. Guess they stopped making their own brand bikes.
