Katrina... Avoidable Tragedy

This is an episode of Cities of the Underworld on the History channel. It's a fascinating look at the effects of Hurricane Katrina on the city of New Orleans and the steps they're taking from an engineering standpoint to prevent another tragedy of this scale. I wish I'd have watched this before I visited last week as we saw many of the places they show, but this really answers a lot of questions I had. It's long (43 minutes) but well worth the time if you're into this sort of thing.... figured I'd share it.
