Thank you for posting this, a subject very close to my heart. Nothing like climbing over a barbed wire fence to feel a sense of achievement when hunting down an obscure ruined tomb (particularly applicable to Ireland where we really did get chased off someone's land once).

The Book of Trespass by Nick Hayes is on my 'wish' list. I know you shouldn't judge a book by its cover but it really does have a good one.
Have also signed the petition.
My trespass days feel as though they may be a thing of the past in our strange new world but (like planting trees) we hand the baton on to the next generation.
Another little book people might like to read is The Fish Ladder by Katherine Norbury - it is actually her own personal story which she weaves around following various rivers in the UK back to their source - the most northerly one being Dunbeath which takes her to Loch Braighe na h'Aibbne. In another instance near the source of the Severn she steps into a puddle which turns out to be a bog and is covered completely with muddy water - fortunately her young daughter is with her to help her climb out.

I like to think my mind will always trespass - even when I choose not to stray from the well trodden path.

Superb, thank you for that.

As Cope sang so memorably in Autogeddon Blues, "It's a barbed wire fence, which side d'you choose?"

Criminalisation of trespass has got to be fought.

'William embarked on a military campaign called the Harrying of the North, an assault on the commoners just shy of genocide. It was a sustained campaign that began in the north of England and set a precedent that was to be followed right up to the nineteenth century. It was a campaign that relied on brute force, the power of the sword and the horse cutting the ties between the people and the land.
In the words of the Conqueror himself:
In mad fury I descended the English of the north like a raging lion and ordered that their homes and crops with all their equipment and furnishings should be burnt at once and their great flocks and herds of sheep and cattle slaughtered everywhere. So I chastised a great multitude of men and women with lash of starvation and, alas! was the cruel murderer of many thousands, both young and old of this fair people.

I had no idea.

The Spring edition of the Ramblers quarterly magazine 'Walk' has an interview with Guy Shrubsole, co-campaigner with Nick Hayes, and author of ‘Who Owns England’. The interviewer asks him about his statement that 92% of land does not have open access and 97% of are rivers are limits.
Guy’s answer is most definitely worth reading. His opening sentence is to say “that we have access to 8% of England is huge testament and thanks to the work of the Ramblers. The Right to Roam is the core of what the Ramblers are built on”. He talks specifically about Scotland later in the interview.

As a long standing member (though I no longer walk with them) I know what an amazing job they do protecting and maintaining historic footpaths. In their magazine there is also an article headed ‘Walk the Line' – tracks across the landscape not only lead us where we want to go, they can also be expressions of free will and works of artistic beauty – and we should protect them at all costs. It lists and describes seven types of ancient footpath which most of us will recognise – Cairned paths (marked by a man-made heap of stones often at summits), Coffin paths (also known as bier roads and lych ways), Desire Paths (informal shortcuts), Drovers’ Roads, Herepaths (former trade/communication routes between remote settlements), Holloways (sunken ancient paths or roads), and Smile paths – I didn’t know this last one. It is a deviation on defined routes, typically around an obstacle such a fallen tree, puddle or locked gate.
I don’t know if the Walk magazine is generally available in W.H.Smith (is that even still in business) if it is then this edition is excellent value for money (Issue 70: Spring 2021, £3.60).

Something I feel passionate about so apologies if I've rambled on a bit :-)
