Getting your point across (With subtle humour)

Driveway in Kelowna, British Columbia

Houses near a beach face a common problem. When the weather gets nice, they are overwhelmed with people parking on their street. How can the residents address the problem? Well, they can get heavy using the police and tow trucks, but I guess that dealing with wayward parking may be fairly far down on the list of proprieties for the authorities.

Or they could do what this resident did and use a bit of subtle humour to dissuade people. Perhaps it only takes something like this to raise people's awareness about the problem. I hope it works for them.
