why is golf the only sport where spectators must maintain absolute silence at all times? They ask for quiet in tennis, too, and honestly that one confuses me a lot more than golf. Tangentially, you would think that in the 21st century someone would be able to invent an affordable camera that didn't make any noise when it captured the image. And if these exist already (I am admittedly ignorant of new camera technology), why not make these the only ones permitted at PGA events?
