Maps with updated info of Katrina-affected areas

I just found Scipionus.com, a site that has a map of all the affected areas, updated by visitors to the site who have information about the people and places in the various neighborhoods in the cities. It's pretty wild. I can go into the Mandeville city map and see what's going on around my friend's brother's church (he's a minister). Yet another ingenious way people are trying to help.
