Hi Mr.Hamhead, it seems there is a certain amount of local opposition to having the moors fenced off, a bit like the old enclosure act of the 18th century.
I think it all boils down to the freedom to roam without there being fences, gates, and cattle grids. I know there is a bit of Cornish nationalism down there ;), and I suspect those of us who would visit stones in far away places will have to put up with bullocks and cross female cows and their young but you know the area so are the expert on this one.... this is the news briefing....
