Open carry is perfectly legal in Louisiana, but I don't OC unless I'm in the swampy woods on my grandfather's property. Out there, you need to carry some sort of firearm for protection from both animals and people, since armed tresspasors looking to hunt on other's property is not uncommon.
I'm not old enough to get a CCW, but when I am I will. Carrying is not necessary most of the time for me. I live in a very safe and peaceful community. However, for hurricanes, floods, or if I have to go into New Orleans, carrying is a very good thing. Open carrying in public however just doesn't seem smart to me. Why bring a lot of unneeded attention to yourself, or make yourself a target? I would much prefer people not knowing I am armed, and just passing under the radar.
