Believe me, I am familiar with ALL parts of the city and surrounding parishes and the destruction that occurred in each. BTW, I can show you other areas that were equally, or more, devastated than the Lower 9.
Examine his/her itinerary carefully and you'll understand why I suggested "The East" with the easy off/on. They want to drive from Baton Rouge after a peek inside Tiger Stadium, "visit" New Orleans, do a quick "Devastation tour", stop in Biloxi at a casino for a few hours, and continue on to Pensacola in less than 24 hours.
Actually, with that kind of itinerary, my suggestion would be to skip the "Devastation Tour" because, pardon me, I think it is a little disrespectful of what happened to our citizens and our great city to only spend such a brief amount of time viewing the destruction and thinking that you now understand "it". Those of us who have lived here all of our lives are still trying to understand "it". Sorry for the rant....
Anyway, I hope the original poster and father have a great road trip and get to see & do everything that they want.
