Well, you can’t argue with a sign like that. After all, you wouldn’t want a park ranger to come round and tell you off, would you? There’s only one thing for it: putting your poor pooch in the trash. Sorry, Fido, it’s the law.
This is about as specific as a sign can get, so really, you can only applaud the person following it to its absurd extremes. In fact, it’s so specific that we can’t help but wonder whether the sign was actually erected after he turned up with his pad. Sadly, we’ll never know.
If you’re going to make a massive list like that, you’ve got to make it fully comprehensive. Of course, it’d be easier just to go with “no wheeled vehicles,” or some other catch-all term. Otherwise, you end up with smart-ass dudes like this. Still, you can’t blame him for being inventive.
