If I understood correctly, the current owners have only been here about 10 years... the wonderful Google AI reckoned that "although it's private land, the farmer tolerates access"!!! - hence me deciding to make my way through an open field boundary to step over a wire fence.... no signs, no indication that visitors are unwelcome... nothing. So this would maybe suggest inexperienced, relative newcomers who are not 'fitting in' with the local community as well as the previous owners, perhaps? Could be wrong, of course, and they have really suffered some extreme nonsense over and above what 99% of farmers would take in their stride? I'm well aware from long experience that South Walian towns can be 'difficult' if you don't abide by certain rules....

However, talking to the owner at length, I actually got the feeling she was - deep down - quite a reasonable, caring person - e.g seemed genuinely interested when I mentioned the wealth of upland burial cairns in South Wales. She DID also allow me to stay and take pictures once I'd calmed her down.
