It's been a while since I saw an apocalypse role play fleshed out this much right off the bat. I like the sound of it so I'm just going to toos my interest in for what it's worth. 

I do have to say though, that it's really cool that you've thought about PM'ing individual players to talk to them about things they may have seen pr what they find so that not everyone has to know. It keeps things mysterious and fun ;)
