Wonkette indicates that the photo is from the Austin airport garage. Pretty complex paint job -- two color! And pretty steady lettering. (You ever tried writing this kind of stuff on this kind of surface? Ain't easy.) But then 'to euthanasia' for 'to euthanize' and 'whom' for 'who', in the span of nine words. Almost makes you wonder if it's real, in the relevant sense ... . Hey, maybe it's more brilliance from the Arizona Department of Education.
