For clarity: Britain these days, if you believe popular culture, is plastered with warnings and notices. Don't do this, warning, forbidden, fines, notice, etc.
No matter where you go or what you do, there's some sort of warning about what you shouldn't do, what is dangerous, what is forbidden, and so on, and so forth. I do recall an abundance of such notices when I was last in Scotland, over a decade ago. Keep of the grass ain't the half of it.
Well, someone decided to do this. It's not just quirky, whimsical and a bit, dammit, I can't think of that adjective, it's on the darn tip of my tongue.
Anyway, it's a very British solution to the problem of an over-regulated society, I think. It's like something from a Douglas Adams or Terry Prattchet novel.





Except for this one, I don't much like this one...no need to actively encourage people to do that, I say.

These are just the highlights, there are a few more when you follow the link.
