After living on the same street for over 45 years, the city thought it now necessary for some reason to put up this guard rail; in all that time, I have never known of a car to go over the cliff; the only incident I remember was back in the 60's or early 70's when one of the neighbor kids who was walking along the edge fell and broke his leg but other than that it's been incident free. I wonder how long it will take before graffiti art covers it.
