Bring a raincoat
Clothing/Shoes/Weather Gear: It rains often and without warning in Louisiana so bring rain boots, a rain coat and an umbrellia. It is normally very warm and humid here so dress in layers, shorts are a must but I also suggest a light jacket because spring and fall are sometimes prone to cold snaps and could also become cool at night. I always suggest comfortable walking shoes and sunscreen is a must...
Luggage and bags: It depends what the purpose of your trip is. If you're a conventioneer, bring a carry-on for business suits. If you're headed to the bayou, you won't need such formal gear.
Clothing/Shoes/Weather Gear: RUBBER BOOTS!! Central Louisiana is a muddy place, to put it mildly! Hunting and fishing abound, so pack for whatever you like to do. Louisiana is called the 'Sportsman's Paradise'!
Toiletries and Medical Supplies: If you have a rental car, you can get whatever you need at the huge Wal-Mart in Pineville or at the Alexandria Mall which is a typical shopping mall that has most of the nation's major chain stores. Alexandria may be seem to be located in a remote area compared to New Orleans, but it is definitely connected to the rest of the world via cable TV, internet access and cellular telephones.
For some reason, Alexandria-Pineville is a big center for hospitals and medical centers. My cousin is an emergency room nursing supervisor and she's doing just fine there. I wasn't able to determine the reason why that came to be, possibly to serve the former military base? It was a big mystery to me, one that my cousin couldn't explain, either.
Photo Equipment: If you get out of Alexandria, you will definitely want to take photos of the bayou and countryside. Again, there are enough chain stores that supplies shouldn't be a problem here.
Camping/Beach/Outdoor Gear: Are you ready for the country? If that's where you're headed, plan to bring hunting and fishing gear!
Miscellaneous: The last item I want to mention is the CHEAP real estate in this part of the country. You might want to keep a notepad in your luggage, which is handy to jot down prices for future reference. Homes in Alexandria start in the $45,000 range, which is major culture shock to someone like me from the Northeast. This would be of definite interest to people on fixed incomes!
