Today's assignment was to rotate the camera a bit and make a slightly off-angle photograph, making sure the angle emphasizes the subject.
According to Wikipedia, the concept of fire plugs (or fire hydrants as we know them to be) dates to at least the 1600's . This is a time when firefighters responding to a call would have to dig down to the wooden water mains to quickly bore a hole to secure water to fight fires. The water would fill the hole creating a temporary well, and be transported from the well to the fire via bucket brigades, or later, via hand pumped fire engines. The holes were then plugged with stoppers, normally redwood, which overtime came to be known as Fire Plugs. The location of the plug would be recorded or marked so that they could be reused in future fires.
