Until moving to New Orleans I had not seen mass quantities of street barricades before. In New Orleans they are professionals in setting up and taking down thousands of barricades for Mardi Gras and many other occasions. But, until seeing the Paris pros lay a line of barricades using a crew and a mechanized truck, I thought New Orleans was on top. This Paris crew laid down a line of barricades over 100 yards long in under four minutes. I was amazed.
