The note in the box:

If you are reading this... I don't know. Not sure if you're still alive out there. If you are -- I haven't found many others. It is just my wife and I at the moment. We've managed to gather some supplies though, if you can believe that.

My wife and I... we're alive. We're at a fort about 10 miles outside of Manhattan, right on Staten Island. We tried to venture out further, but we were attacked. Walkers just came out of the woods.

They're spreading. We lost everyone, Don. Watch yourself.

I think we should head for KPPC. If you get this, we'll meet you there. I've sent you some of the supplies that we could spare.
