Apparently, the ravening hordes of the undead will be attacking downtown Detroit this week. They have a website (zombie claus) and everything. Afterwards, there may be bowling.
I, for one, welcome our new zombie overlords . Dopers, beware, they are after Braaains, I may not have the good luck to turn undead by the weekend, but I am happy to learn that zombie attacks are more common then I thought.
Did you get permission from the NFL to use that word in your OP?
Anyway, this is all I found pertaining to the OP.
