In reply to Bobling:
A similar thing has happened here in Mid Wales. A public footpath has been re-routed uphill well above a farm instead of going straight through it and then continuing along the valley floor. There are no permissive signs, just proper council FP signs. However, it all seems very rough and ready and although the 'new' footpath leads you back down in the general direction of the valley floor, it suddenly ends on the hillside at the farm's boundary fence. There's no stile or gate and beyond it, on the neighbouring farmer's land, there's an impenetrable area of gorse and a very steep slope separating the end of the 'new' path from the line of the 'former' path's continuation on the valley floor. To get to the original path now involves some desperate downwards scrambling on cr@p rock above an abyss in order to avoid the gorse. Interesting with a dog on a lead I can tell you, especially when eye contact with the beast tells you that he'd much rather fend for himself rather than be attached to an-about-to-fall human desperately grasping handfulls of heather.
Coincidentally, there is a huge, recently built barn now occupying the route of the former path. It's patently obvious that the farmer decided to build his new shed across the line of the FP and has diverted the path himself, using the FP signs from the original path. However, his land doesn't extend far enough to ensure that the 'new' path can return to the valley floor, so it just, er, ends in the middle of nowhere on a hillside.
Having lived in Mid Wales for over 40 years, I realise that such red-neck behaviour is not uncommon in these parts, so I wasn't overly surprised by any of this - although the sheer barefaced audacity and scale of it all is nevertheless quite impressive.
Anyway, I brought this to the attention of the council's RoW dept. They confirmed that there had been no application to change the route of the FP, but on a level of 1-10, their interest level barely scored a 1 and after several mentions of 'chronic under-staffing', 'lack of resources' and 'funding cutbacks' it became crystal clear that they're going to do sweet FA about any of it. Problem is, we also seem to have a redneck county council - and a poor one at that, in every sense of the word.
