After several hundred miles of trying, Greyhound bus passenger Ed Costa finally aborted his attempt to enjoy the Kansas scenery Monday. 'Fuck it,' said Costa, turning his head from the window somewhere around Walker. 'I've tried and tried to derive aesthetic pleasure from the view along I-70, but it's nothing but flat land as far as the eye can see.' Costa said he was hoping to see 'a hill that was even slightly rolling,' but no luck.
