It's my impression that Mardi Gras is celebrated along the Gulf Coast all through February. Here is one doorway in the small town of Breaux Bridge, Louisiana. I was impressed! You will also see Mardi Gras trees (like a Christmas tree, only decorated for Mardi Gras). And, of course, beads. Lots of beads. And, parades. Lots of parades. It's a festive time of extreme partying before Lent. And, New Orleans embraces the partying spirit all year long, but especially now!
