(New Orleans, Louisiana) Southern Decadence, the largest gay festival in the South, had hardly begun when thousands of people Saturday night were told to flee New Orleans as hurricane Gustav continued to barrel down on the Gulf Coast.

“This is the real deal, not a test,” Nagin said as he issued the evacuation order Saturday night. “For everyone thinking they can ride this storm out, I have news for you: that will be one of the biggest mistakes you can make in your life.”

Gustav already has killed more than 80 people in the Caribbean.

Nagin’s evacuation order is the first test of a revamped evacuation plan designed to eliminate the chaos, looting and death that followed Katrina.

The city will not offer emergency services to those who choose stay behind, Nagin said, and there will be no “last resort” shelter as there was during Katrina, when thousands suffered inside a squalid Superdome. The city said in a news release that those not on their property after the mandatory evacuation started would be subject to arrest.

Many residents didn’t need to be ordered, with an estimated 1 million people fleeing the Gulf Coast on Saturday by bus, train, plane and car. They clogged roadways, emptied gas stations of fuel and jammed phone circuits.

Southern Decadence, held over the Labor Day Weekend, regularly attracted more than 100,000 people and had been one of the city’s biggest moneymakers. This year, attendance was lower, as concerns mounted that Gustav was heading toward the Big Easy.

The party has had its detractors in a city known for hard partying.  In 2003, the state legislature passed a new indecency law that bans public nudity.

The festival also has been the target of evangelical preacher Rev Grant E. Storms, who leads a small group of demonstrators through the throngs on Bourbon Street. In the wake of Katrina some conservative church leaders said the devastation was the result of God’s wrath on gays.

Most people fled New Orleans as Katrina approached, but a small number of people remained in the city, and amid the destruction a small parade behind a tattered rainbow flag made its way up Bourbon Street in an unofficial celebration of Southern Decadence.  The group – about two dozen people – all said they lived in the largely gay French Quarter.  Defiant, they said they were not about to flee the community despite orders from the city to do so.
