Hi Everyone, We have a website up for our infrastructure mapping project here at George Mason that might be of interest to some of the folks on the list: http://policy.gmu.edu/imp/ Also I though we would add our little take from the thread a while back that asked if our maps showed the 2003 blackout. While is is hard to show a cascade or predict a blackout I think the maps do point out some structural vulnerability where the cascade started: http://policy.gmu.edu/imp/research.html (Map #6) If the work looks helpful to anyone or if you have an feedback please pass it along. best, sean
