On ITV4

Half of America has been hit by nuclear bombs, they have no infrastructure as such, yet no one is bothered about fall out radiation?

Also no nuclear winter and no troops. If they hadn't made it clear at the start of series, you'd just think it was an extended power company strike.

I don't know where ITV4 is up to, so therefore I don't want t o spoil anything, but I think some of your questions will be answered. Also, additionally, they're bringing Jericho back... woo hoo!
