It's not a matter of building tracks that go to no where, its not a matter of holes on the side of tracks, or building in an area that looks eroded, its building new tracks in the first place with complete disregard to maintenance of other lines that's the issue. In reality, some areas may be eroded yes, but seriously, hacking half the vegetation off the hill is hardly going to help the embankment stay stable.
The key really is educating ourselves in sustainable trail building and maintenance, and in inconspicuous ways that don't draw attention to ourselves. Really guys, we have been told time and time again what was going to happen and now it is. We need to wake up to ourselves, see what's happening and realise that we need to move forward, not start conflict. The term borrowed time has been thrown around loosely for a while, and now it seems that time is up.
