From the Wikipedia site:
"In March 2004, Aliso Viejo, California almost considered banning the use of foam containers at city-sponsored events because dihydrogen monoxide is part of their production. The issue was put on the agenda of the City Council after a paralegal found mention of DHMO online and did not realize it was a joke. The item was pulled from the agenda before it could come to a vote, but not before the city received a raft of bad publicity"
About the same time, Fluor Corporation (onw of the world's leading engineering and construction companies), made the decision to move its corporate headquarters from Aliso Viejo CA to Dallas TX. Whether or not there is a question, I don't know, but I can just hear Alan Boeckmann (CEO of Fluor) responded to this with "WTF?! It's long past time to get out of California!
