How to Rate a Bar-B-Q Restaurant

As we travelled on our journey to D.C., we had occasion to discuss places to eat. In trying to determine which would be best, Wendell and I got on the subject of Barbecue. Since we had never heard of some of these places, we pondered how they would compare to our local favorites.
We just so happened upon a billboard touting a local smoke-pit, prompting Wendell to exclaim "That place HAS to be good-- They have THREE pigs on the sign...!"

Made sense to me.
