I was born in New Orleans, raised in Fort Worth from the age of 5. Parents are from Hammond and Covington, La. I spent a lot of time as a kid in Louisiana on vacations to those places as well as Lafayette. No shortage of good food, and it will be very easy to find.
I'm an airline pilot now, but 20 years ago, my first flying job was flying canceled bank checks around in the back of Beech Barons. I was based in New Orleans for a year, and my route took me to Houma 5 days a week to pick up work and head to Baton Rouge. Hammonds Flying Service was where I would park. Mr. Hammonds's son was in the Navy and was a Top Gun instructor. He flew the Migs in scenes in the movie "Top Gun".
They were very nice people, which is what your son will encounter while in Houma, I'm sure.
