I'm with you on the Denver issue Cass! I really think that the reason the Prez and gang will be in Denver is because of all of the stuff falling out of the sky. Most reasonable explanation for me. Normally the impending Govt shutdown would be PRI 1 for the Prez, wouldn't you think? It must be something serious to supersede the govt shutdown. NASA being in Denver also, tells me that this makes the most sense. They are taking precautionary measures maybe?
