One good way to get a lane closed.
It's a pity that some people just don't give a toss about responsible laning, its a cracking view from the top and would be a real shame if it was lost due to the actions of a 'few' tw@s
GLASS teams spent the weekend on the Wayfarer putting huge boulders in to stop all the off piste activity.
I now seems that, within a day of them finishing, someone has winched the boulders out of the way and driven off piste.
Can you set up something like a trail camera to catch people in the act of moving the boulders etc? I use them for recording deer and they work great night and day.
