About a week ago the Times Picayune showed a 1879 topographical drainage map of New Orleans. Then they displayed the areas of New Orleans that had just flooded after the levees broke. The two maps were amazingly similar. In other words, if we had only built in areas that were deemed high ground on the 1879 map we would have been mostly okay. If you want to take a look at the map click on this link and then look at the T.S. Hardy map. There are other interesting maps at that link.

It seems that those who do not read maps are destined to redraft them. It’s good to see you your blogs starting to sound like old ironic Ernie.
