You know what I found odd? It's supposed to be a nice neighborhood, right? Madison's house is very open and exposed, but when Nick was looking to break into a house for pills, both it and the one next to it had security bars on all the windows. Nice ones, yes, but still - they didn't seem like they would be on the same street.
And btw, if one of those houses with the window bars was empty, that's totally where I'd be bunking down. That is some good zombie defense right there.
