You wouldn't (and shouldn't) get away with that now! Signs are mandatory in public access areasContacted a live wire with the back of my neck. Didn't like that much. No signs and it looked like it was fixed around a tree. High up above a retained bank and obviously aimed at stopping kids escaping the campsite into the field. Didn't work too well but kids often got caught out once before they got a work around. Almost 40 years ago.
