City Signage: How not to do it

So, FailBlog presents us with another classic. Seriously, was this guy high when he created the sign? Did someone have a 2nd grade math problem to do and had no paper? What kind of unit is this measuring? Talk about "apples to oranges"...or more like "apples to random summation of incongruous units". Good job, California, you have yourself another winner.
