Warning about Cameron & Calcasieu Parishes
It hasn't been in the news very much (overshadowed by Katrina and N.O.), but most of Cameron Parish is destroyed and Calcasieu Parish (this is Sulphur, Lake Charles, etc) was heavily damaged by Rita. My sister goes to school in Lake Charles and said the damage is unbelievable (don't get me started on McNeese reopening 7 weeks after the hurricaine with 40 buildings destroyed or severely damaged and still demanding that the students finish the semester on time).
It will probably be ok by next year for travel, but she said that there are hardly any trees left in Lake Charles, so I imagine that there are very few in Cameron. Cameron is south of Calcasieu, therefore, was much more heavily damaged.
But, N.O. to Miami. 17 days is more than enough. I've driven from N.O. to New Smyrna Beach, Florida (about midway through the state) in 18 hours. Granted we didn't stop and see anything. I checked the other day and Oak Alley and Laura Plantations (take the Gramercy exit West of N.O. from I-10) are fine and are must sees. If your are heading towards Lake Charles anyway, stop in Lafayette. Just south of Lafayette is New Iberia where Shadows on the Teche is and the Avery Island Tabasco production plant gives tours (not sure about damage through there). Try the jalapeno ice cream!!
