... do this, dont do that, cant you read the signs?
Even on a lovely walk through the park, there is a sign telling you what to do. It looks like this one has seen better days, maybe some disgruntled dog owner didnt like leashing up their dog and took it out on the sign.
*UPDATE
Ahh, the irony... the sign has actually been removed, so I have moved this cache to a magnetic spot nearby.
