McCarran Airport in Las Vegas

After a successful flight from LAX to Las Vegas, I arrived in Las Vegas at 8:12 AM. I found out that my 8:56 AM flight to Chicago was canceled. After calling the 800 number (the United computers at the airport were down!) and talking to the ticket agents personally (once the computers started working again), it was determined that the next flight to Madison is 7:02 AM (next morning) from Chicago so..... I have been waiting for the past few hours for a flight to Chicago that will leave at 11:25 PM. WTF is that? Like 15 hours of stupid sitting around at the airport.

They're giving me a stupid $125 voucher to save on my next flight with United... uh, do I really want to fly with United again? Grr and I also had to buy unhealthy and overpriced airport food too. This Wisconsin trip did not start off well. GRRRRRRRRRRRRRR!!!!!!!!!!!!!!!
