NASCAR again returns to a 1.5-mile track this weekend at Kansas, and we must ask: does the sport have too many of these cookie-cutter tracks? We also consider similar head-scratching questions like: Is air good for you? and Is the sky blue? But what other options are there? Ah, there's the rub. Your favorite Yahoo! Sports Jays, Busbee and Hart, kick around the cookie-cutters ... for at least a mile and a half. Enjoy.
