Forgive my ignorance, but I don't entirely get it. Having come from Canada, I understand that if I rode my bike across some farmer's filed, he could set the dogs on me. I have since ridden in both England and Wales, and just stick to the trails on which I am allowed, including when they traverse a farmer's property. As I understand it, that is something that has been possible since, well, forever.
How is access different under 'Right to Roam'? Does it mean that, in Scotland, and eventually Wales, you can just ride/camp on/ramble across anything you see? And does it only apply in rural areas? I mean, whatever the nature of the law, I assume it doesn't mean that someone could just show up in my back garden!
