How the hell did all the zombies get onto the roof of that store???
With the helicopter up there I'd say they were people that died in the crash maybe?
Exactly.
As for the crazy lady in the woods, I think that it had a deep meaning to it....perhaps Rick relating to her in the sense of his love for Lori and his keeping her alive with his hallucinations about her and this lady's love for her husband and her sense of keeping him alive by feeding him. Just my take on that whole plot with Rick and the crazy lady.
