New Orleans: Vampires Move Out

The current crisis in New Orleans is an apalling tragedy. Once again, the poorest are bearing the brunt of the suffering. My heart goes out to all affected.
When I think of New Orleans I think of three things:

• Poppy Z. Brite
• Jazz
• Vampires

The first and third of these are related due to the topic and setting of the Brite novel I've read. I guess the vampires who have lived in New Orleans for centuries will have moved out while the flooding persists - or perhaps they're surviving on the easy prey of the vulnerable?
