That southern route (I-49 Corridor) is a safe route but is mostly through swamps. It is elevated over the swamps, but those bridges make for some rough shelter except under the exits. The skeeters are Baaad! Most of the high ground between bridges have sparse tree groupings. Clean water sources would be scarce or non existant. All local water is easily treatable though. The natives are non hostile but not overly friendly to strangers. My Parisian French is not Cajun enough to pass the locals but sufficient to communicate accurately.

I believe following the Levee northward to Hwy 190 is the preferred option but the I-49 Corridor is an option.

Thanks for reminding me to get bug spray if I had to leave!
