The Mayor of Pasadena got a good laugh (and sparked some serious discussion to boot) at IJCAI 2009 (<a href="http://ijcai.org/~ijcai09/" rel="nofollow">http://ijcai.org/~ijcai09/</a>) when he proposed something like that. There's often an opening "I'm the mayor and thanks for bringing some convention dollars to our city" speech at large conferences, which is usually horribly boring and full of platitudes, but his was short and more or less said, welcome to California, I wish you all luck in developing artificial intelligence, because we're currently looking for a better government.
