The charge is essentially an idiot tax. Though have a slight fear that some paying idiots might start informally policing the thing, seeing it as a "cover charge" to keep the oiks/riff raff out.
What would the mass trespassers think of this state of affairs?
Such is the state of things these days.
I won't be paying it - I wouldn't dream of paying £20 on a campsite for me and my bike.
They can stuff it.
When I have a mo i will email them from that site telling them in no uncertain terms what I think of this, telling them that I see this as permission to camp in the parks, that is no longer a no no, reassuring them that I will pay them not a bean but that I will definitely leave no trace and will treat the land, but not them, with respect.
And suggesting they read some history about the british people and their access to the land.
Thanks for posting this pete.
