Look out below!

Katrina may be heading for New Orleans. Big city. Below sea level. Catastrophe waiting to happen. And I still don't know why they can't figure out how to use both sides of a freeway to get people out of town quicker.


[Update 3:45 pm] Reader Margaret points out that New Orleans did learn from last year--they ARE using both sides of several freeways to evacuate, using exit ramps as on ramps. Thanks, Margaret!
