I figured the 1911 was a battlefield drop from the Governor's attack last season. It looked to be in too good condition to have been buried there too long.
Time to look through Tivo'ed episodes from last season and see if anyone in particular was carrying it? I'm never sure what's a future plot revelation and what's a throwaway visual in that show. I guess that's one of the aspects of the show's writing that makes it so worth watching.
I dontknow it was buried pretty deep to be from last years attack ,although I do agree it seemed to be in good condition

I would say the zombie infecting has mutated to animals and that mutation has a different effect on humans. I wouldn't be surprised to see a scene like in resident evil.
