Street signs can tell you a lot of things- to stop or slow down, that animals may cross the street, and which turning direction is less likely to get you killed.
However, this is the first time that a road sign has taken the time to let me know that bloodsucking ghouls are real.
Thanks, NW Natural! I’ll keep an eye out!
Postscript: Apparently, The Huffington Post has disproved the existence of vampires. Which is why vampires hate math!
