I was there!
I have a slew of pics and a first-hand account of the bloody viral marketing stunt the second season Showtime tv show pulled in a tourist-trap area of Boston yesterday, but I am not at my computer at the moment. So for now, read this and check out their photo of the blood fountain.
I asked who came up with the idea and got the name. Again, it's at home. Will post pics and details later.
