You'll happily pay in England though?
Continuing with tongue firmly in cheek; hope you are not presuming to know where my mother was, as I was born? Nothing to do with me either, I didn't choose my parents, I'm just part of the wildlife. . . and I don't need a rag on a stick to tell me who I'am. . .
I have been known to pay for a hot shower when the weather is cold. Particularly in Europe where their is a less profiteering attitude to this, but also where wild camping is even easier.
As previous posts have said, people make quite an issue out of wild camping. I don't think there is much advice to give that common sense doesn't already provide a guide for. You just have to pluck up courage and go for it. After all no-one is going to tell you the particular spots they choose.
