I passed by this at the end of the start of Jan and took a close look. Coincidentally there was a large gap in the fence!

But that's new, and I suspect will soon be repaired to keep cows in. I still wouldn't go into that field without good quality wellies. The only thing left to do is micromap the fence, and the ditch(effectively a 2nd barrier!) that runs where 25 claims to be. Plenty of that sort of mapping to be done around here.
