Quick note, because Heather and I forgot to mention this in our excitement to get this plot started. The timeline for the zombie plot is a bit futuristic, but not extremely. We're going with the idea that it takes place in 2015, about a year from now. So anything that could have happened this year you can use in your threads--the zombie stuff built for a year and then came to a head.
Sorry if there was any confusion! And don't forget: if you haven't yet, go comment on the previous post with the status of your characters!
