For a month my course pulled the flags and added spacers in the cups due to the Covid 19 pandemic. Several times a round putts that drop perfectly in the center of the cup pop out. The putt counts! Finally on the last day without flags I jarred it from 204 yards, but just like a 2 foot putt it popped out. 24 hours later my playing partners have convinced me that it counts as an ACE! Covid Ace!
