Not the official kind but the cheeky, undercover, shadowy stuff. I can't stop building, no clearing, cheeky trails. Every bit of downhill or nice dry open forest I am looking for nice lines, old deer tracks to clear, rocks or tree stumps to build mini jumps off and slabs that are good for drops. I must spend 30% of my clearing instead of riding. I do have a few rules like no destruction of living stuff except bracken or grass, a tiny bit of pruning and breaking off of the dead lower branches of pine trees. I try to make it so nobody that came past would think there was a bike track there when ever possible. Just finishing of my mini masterpiece where you roll down a big slab to a 3 foot drop off, kindly lower on one side so you can build up to the bigger drop, Down a steep bank, sharp right hand berm made from a fallen tree, flat, down another rock slab with a little drop at the bottom hard left and more steepness, open forest and out into the open, down a big rut made by a forestry machine, over a little line of rocks to cross a bog and over a few burns on tiny rock bridges, little up bit and then join up with a super fast steep deer track with drifting turns... Woo Hoo.
I will try to get a film or photos of it.
Questions though. Do you make your creations public or let people find then. The stuff I have done in the UK I would never make public so for me it depends on where it is. I suppose you also need a large, fairly dry open forest near by so that rules out most folk.
