Anyway, shoes won't cut it for those people, if a storm can turn the trailer park into a swamp and mix the sewage around. Everyone needs waders (or actual sewers).
I totally agree with you here. The conditions the people in the article are living in are awful and need to be fixed ASAP. Though if I had to guess, those were probably on the extreme. What I was trying to illustrate though, was that worms are a bit more nuanced than open sewage. If I were a betting man though (and I'm not, but oh man if I put money on the Packers V. Steelers Superbowl, Mayweather v. Pacquiao Fight, and a few other sports events, I'd have a day), I'd say that most cases of worms in the United States just happen because of poor health care practices, both in parts of individuals' lack of knowledge/concern as well as because of how the medical industry is set up.
Edit: Also, mocassins sound awesome. I've seen these shoes shaped like feet and asked someone about them and they said they were comfortable as heck.
