Surely in your many years on this rock, you’ve heard about the phenomenon of spontaneous combustion? And chances are you’ve decided whether it’s bogus or not, right? Well, we’re here to tell you that spontaneous combustion happens. Just head to the Passenger Terminal downtown, you know, just past the Market, a little ways away from Fleet Landing. Go down there on a sunny day when a cruise ship is in dock and you can see the tourists baking in the sun — and explode into flames if you squint just right — as they wait for a taxi or a shuttle to pick them up. Vampires do better in the sun.
