re: What SEC State is the biggest shithole?

It's a joke, based on an old myth.

The myth is that some company wanted to build a plant or refinery around Vicksburg. Huey Long said that's fine, but you won't be able to get there, and built the old bridge in Baton Rouge too low for ocean vessels to pass.

It is true that ocean vessels cannot pass that bridge, but due to a bunch of geological witchcraft that I don't understand, the river can't be dredged north of Baton Rouge, so it's barge traffic only.
