I knew the general from the Battle of New Orleans song -- so much fun. For some reason, I thought Mardi Gras but didn't type it because I thought it was a week, not a day.
^ Mardi Gras (Fat Tuesday) is, in reality, only one day. But I understand that, in Louisiana at least, the entire three day celebration is now called "Mardi Gras". In most other countries it's called Carnival/Carnavale.
My home state, too (at least my birth state). Although I didn't try it for an answer I was curious to see if it would have accepted what many (most?) natives call the Superdome. All my relatives just call it 'Dome'.
