The lane is 3/4 mile long constructed of stone topped with tarmac planings, they won't get stuck as they are in tractors.
I have tried to find out via land registry but no joy as has'nt been sold in last 70years, neighbours have right of access so I believe, to visit their livestock ,though they don't keep stock in these fields and as i said can get to the fields through their own land without using the lane.
Thanks
