By way of explanation for this post: People started a track through the grass, which the owner didn't like at all, so he created a wooden barrier. Promptly, people (very likely the same ones) went around that barrier on the wrong side. So he put up a fence and attached the water(?)-filled rubber glove as kind of a visual reminder/threat/amulet/talisman/whatever ... It'd be hilarious if it wasn't so irritating (the behaviour of the trespassers, not the glove ...).
