There's still time to go to New Orleans for Mardi Gras on February 28th. The economy there can sure use the infusion of tourist money considering the devastion. If you go, have fun and consider taking one of the devastation tours, taking tons of pix and be a pest reminding people that the area is still decimated and thousands and thousands are homeless and jobless. Katrina charities still need your help.
Here's some links you might find useful if you are considering going:

Cafe Dumond, the historic place for beignets and coffee with chicory. The Decatur Street shop is open.
Cafe Beignet, from what I'm told is the best place for beignets and coffee and chicory, daquiris and fried catfish po'boys. They also have vegetarian offerings and music.
