[math-fun] 177 million tons of ice???

A front-page Sat., Sept. 17 story on the NY Times website, found at http://snipurl.com/hqxi, claims that FEMA has delivered 177 million tons of ice to Louisiana, Mississippi and Alabama in the aftermath of hurricane Katrina. Is 177 million tons a credible amount? Seems very unlikely to me, but I'd like to know what others think. --Dan
