Tomorrow, the 25th April, is the 80th anniversary of the Kinder Trespass, one of the world's first environmental protests. Upwards of four hundred working class ramblers marched over a property line to protest the closure by wealthy aristocrats of grouse moors and ancient footpaths where the 'right to roam" had long been thought an inalienable British right.
As a result, today there are no such restrictions and free access to mountain and moorland country is untrammeled throughout the United Kingdom as a matter of right.
I have a family connection to this important piece of British history. My paternal grandfather was one of the organizers.
