The Lower 9 is still in major recovery mode. If you want to drive a little farther down the road (5-10 minutes) into St. Bernard Parish, you'll be able to see another very hard hit area that is still in recovery mode.
If you want to see what is "possible", drive through the Lakeview and Mid-City neighborhoods of NOLA. Drive down Harrison Ave. between Canal Blvd. and Marconi Dr. and look at a commercial district (restaurants, shops) that has had a fair recovery. These areas experienced major flood damage, also. But, the people really rallied and invested their blood, sweat, tears and money.
Have a nice time and save Bourbon St. for another visit.
Want to add: Get out of your car and go into some of the restaurants, shops, bars, etc. Start up a conversation with the locals. Don't be shy. We'll be happy to talk to you and share our stories.
