The right to roam movement is explicitly about responsible access rights to most of the countryside. As a whole hearted supporter, I agree that the situation is indefensible and needs fixing.

We are essentially excluded from land through centuries old stitch ups intended to exclude the common man. It's stuff that goes back to the Norman conquest when the elite essentially carved up hunting lands for their own benefit, with subsequent enclosure after enclosure that destroyed commons rights.

The intent of the Right to Roam movement is to reclaim some of what was taken from us as a whole.
