If you fancy a little further reading, you should google the Kinder Scout mass trespass of 1932. A fascinating story, and one that led to the creation of Britain’s national parks in 1949.
It’s hard to believe for me, born much later, that before 1949 a pleasant stroll in the country would have left me breaking the law. Incredible really.
It's things like this that make it obvious to me why we are over here and you are over there. A pleasant stroll in the country isn't a human right. But if you have no place of your own to stroll, what is so difficult about asking permission first? I hike a lot on other's land and I've always asked permission first. I've only been refused once. It's just common courtesy.
