In Louisiana, you can carry into a restaurant, as long as you don't carry into the "Bar area" of the establishment. On day I was meeting my wife for lunch at a TGI Friday's that had just opened. It was really crowded, so we went and sat at the bar. As soon as I sat on the barstool, I felt my CCW shift into an uncomfortable position, and I realized where I was. I pulled a "Honey, I left my cell in the car...be right back" and glove boxed the CCW.
Last weekend, I had volunteered to help out with a Mardi Gras Parade (a smaller one that went through several bad parts of town. I really wanted to take my CCW, but Loiusiana prohibits CCW's at "any parade regulated by the gov't", so I was torn. Luckily, i ended up with the flu :barf:, so I couldn't go anyway.
