The horns have to be blown, and loudly, when the fog comes in like it has the last three days, because just here the river does its tightest turn, at Algiers Point. A restaurant used to stand on the opposite bank, on that tiny peninsula jutting into the river. You could sit with your cocktails and your meal and for hours watch the giant ocean-going vessels make their way around the point.

It is a masterful dance. The river pilots first power into the turn then suddenly jerk hard to port, the stern sliding all the way around with the bow locked in place mid-river.

Sitting at dinner looking through tall glass French-shuttered windows, the vessels literally pivoted around your table.

It was dizzying. Then, just at a precise moment, the pilot gunned the engines full ahead, to fall instantly again into the deep straight vessel channel as the river passes the Vieux Carré.

It is a frightening manoeuvre in the broad daylight. It is a miraculous combination of engineering and intuition in the dark and fog. And they must stay out of each other's way, these huge moving structures, as long steady lines of ships both come in from, and travel to, the Gulf of Mexico at every hour of the day and night. Through the heart of New Orleans.

Thus this morning's symphonic dirge.

When I finally climb from bed, the slowly evaporating fog has already softened the many ragged post-Katrina edges that remain in the neighbourhood all these months later. An orange glow tints the thick wet blanket of moisture as the sun finds its way slowly to mount slate-armoured rooftops.

This is a rougher place now. True, it is populated by much the same stubborn, ragtag army of carpenters and sculptors, plumbers and painters as before the hurricane. Hell, I live here. But there are new elements, strangers from all over the country, all over the world, walking our streets, looking to cash in on the goldrush of federal money and cheaply-purchased ruined housing.

It is rough, but the Faubourg Marigny has kept itself a simple haven of blue-collar magic and metaphor. This is the neighbourhood where Piety street and Desire street run side-by-side for dozens of blocks, parallel, never meeting, until they come to an end just as they cross Pleasure street.

New Orleans is a city that lives in metaphor.

I am drawn to the levee mid-morning, a short walk, chicory-bitter creamed coffee in hand. A warehouse and dock sits atop the large earthen mound, the water, mimicking the color of my beverage, lapping at its edges. This is the levee that held, and continues to hold, the Mississippi river within its confines. It has my personal confidence and gratitude. My home took no water in the epic of 2005.

There is a spectacle to be seen now that matches the dawn's music. Just offshore the river is topped with a milky, opaque fog a mile long and six to ten feet deep, running completely from east bank to west, brim-full to the top of the high levees. And as I stand there, each of the passing ships makes its maneuver into the turn with its stern swinging broadly, forcing a wide stream of the fog to move toward the east bank where I stand. As it hits the levee it rises, a low-hanging cloud spills over my feet, reaches my waist, and flows down into the neighborhood.

A thick cream off a cappuccino rolls into the streets.

The same water that drowned us, that destroyed our homes, that poisoned our parks and trees, she gives us this beauty today.

I wrote once some years back about the foghorns. I tried to fabricate metred lines, speaking of them like some huge herd of mournful whales, traveling downriver with their echoes, singing to one another as they tried to once again find deep, safe water.

I am now glad to have lost that bit of writing.

Poetry has no place in this city, not for the moment. These are more literal times.

And today, I look at the water and am grateful.

There is nothing else to do, is there?
