Seems that BART is now catering to pirates too. Not the modern kind that “steal” music, videos or software, but the more traditional kind that wear eye patches and walk on wooden legs.
In case any of these pirates take over the train and need to get rid of some of the passengers in a hurry, there is an emergency plank that they can be made to walk. The sign on the door shows very clearly where it is located, and which direction victims should be made to walk. Captain Jack Sparrow and his fellow pirates should be very happy that BART took their needs into consideration 🙂
