Recently i came upon an article from the american newspaper the telegraph published 5. Feb 2009. From this article the picture is taken.
As you see there was a coincidence including some Zombie activities, but there are no further sources available. Later it was dementet, saying that the writings were pranks, placed there without permission. But in my opinion the fact that there is hardly any material about the coincidence in the internet shows that there is some secret hidden about what happened there in Februar 2009. So we will have to look out, perhaps the day Z is sooner as we think. Please share your opinion, when you have a guess when the Z-Day will come, share it and i will collect and publish.
