the sales tax is 7.5% in the State of Loosiana, and an extra 2.5% in Nawlin's. On a very few days a year, and Labor Day is one of them, there are NO sales taxes on guns! The Academy and Bass Pro Shops are gonna be absolutely nutz!
Louisiana has Open carry with No Permit just like Wisconsin, there aren't any butthead sheriffs like in Madison, WS.
One other thing I found out, which I had assumed was like Minnezotah, and it isn't. You have a constitutional right to carry a loaded firearm in your vehicle, period! No permit, no hassle. The only exception is in DNR controlled hunting zones.
