...otherwise it's just going to get worse. I Marshaled at the 2000/2010 U.S. Opens at Pebble Beach where Restrictions/Bans were enforced...no one suffered...and as the Masters' total ban shows it can still be implemented elsewhere. The USGA loosened its restrictions at Chambers Bay in 2015 by allowing cell phone usage only at designated locations on the course...if someone were to violate that rule, they would be escorted out of the premises...personally, I'd like to see the total ban implemented.

Note that the Juiced Up Yahoos will still be in attendance, but muted.
