Apocalypse anyone?

So ever since we made these weird videos for a youth retreat about a post-apocalyptic world with a female cannibal biker gang I've been wanting to do some sort of post-apocalyptic rp.

Rest assured, I don't necessarily want to include cannibals or anything mentioned above. The main idea is that it would be a world where pretty much everything has been destroyed. Those few survivors would have to scavenge to survive and there would basically be no order or government of any kind.

At the moment I'm thinking that this would be set a little while after the apocalypse or whatever so it wouldn't be like everyone's unsure if there are other humans out there. There would be a decent number of people, but the cities are by no means crowded (I'm thinking maybe two-thirds to three-fourths of the population was wiped out). Basically there are enough people that some have formed little gangs and it would be rare that you would go all day without running into someone else unless you stay hidden or something.

So, thoughts, ideas, would be much appreciated, but most importantly I need someone to rp with! I'd like this to just be a one-on-one rp but if a couple people really like the idea and wanna rp that's awesome and that will be perfectly fine.
