When I were a lad, there were signs saying "no cycling, erosion problem" on tracks around a reservoir. We ignored them, they weren't legally binding. Park rangers can't do f*ck all. They also got very annoyed when we swam in the reservoir, some bollocks about them being responsible for us drowning. We ignored them of course. The fishermen on boats got pissed off when we frightened the fish. We ignored them too.
But they're clearing the path for the bikes.
Walk barefoot like me. I can go over any terrain.
