Rowdy fans chant and cheer at the 16th hole at the Waste Management Phoenix Open in Scottsdale, Ariz., on Friday, Jan. 31, 2020. The tournament's boisterous and full atmosphere, the most attended in golf, earned it the nickname, "The Greatest Show on Grass".

The Greatest Show on Grass

The Professional Golf Association's best attended tournament isn't at all typical by golf standards. It's loud, for one, and crowds erupt at any chance. Around half a million people flock to the Waste Management Phoenix Open over five days of heavy drinking, balmy weather and passionate fans, especially at the infamous 16th hole. The unique atmosphere brings quite the spectacle and fan experience.
