Here in St. Louis, Mo there is a section of Highway 21 that is known as Blood Alley. It has a sign that has "Blood Alley" really big on it, a few other things, and a death count. To emphize the death count rather then replace it each time the previous number is X-ed out and a new number is placed next to it. I think the count started at 20 and is now over 30 and the numbers take up almost half the sign.
