Since Katrina, my neighbor Tommy Zander, who is also president of our condo association, has taken it on himself to keep us all informed about the state of the building, what's going on in the city, and so on. This didn't surprise me. He's a retired United pilot who captained 747s around the world, and is quite comfortable assuming command.
Today he sent around something truly interesting, from the New Orleans Times-Picayune. (Incidentally, I think the T-P should be awarded some sort of special Pulitzer for service above and beyond the call of duty, even if one has to be invented for them. Their service throughout this crisis has been nothing less than heroic.) Their website has a .pdf file that is a map of the city showing just where the flooding was, and how deep it was at the worst, the worst being rated as 10 feet and up. Click here to see just what happened. You may need to be patient. As it's a detailed graphic it's a pretty big file, and for those of us still in exile here in dial-up land, it takes a while to load.
