Mardi Gras Revelers Flood Big Easy, Residents Ponder Jump Ship

Mardi Gras has been described as the tale of two cities: New Orleans before and after Katrina.  Last year's Mardi Gras was the first after Katrina, and it was mostly a local affair.  This year's will be a better measure of what's in store for New Orleans. Today is Fat Tuesday, and hotel occupancy is up, but so is the number of cops on the streets because of an increase in violent crime. Many residents who've qualified for government grants still aren't sure if they ought to rebuild or take buy-outs. With the city just half as large as it used to be, we hear about prospects for public safety, race relations and reconstruction.
