Funny that, same thing happened to me. "It's by the gate - the one that ends in a point" was as much description as I got. There's very little distinction between plot and grass path, so it's guesswork. When I went up to mark out some aresa, I was expecting someone to come up and evict me any minute..... but then again - it looks like nobody's done anything on it for quite a while, so should be safe to start digging...
