They failed to see large sections of the course for over three hours in the morning, but when the fog cleared, several of the US PGA Championship's main protagonists could not see the woods for the trees.
Tiger Woods is a figure who has been lost in a fog of disillusionment in recent times, but not yesterday. He was far from the forlorn figure who signed off on the sick after a closing round of 77 left him second from last at last week's Bridgestone Invitational tournament, an event he carried off a year ago.
His doughty 71 served as some kind of example in how to weather the mental storms of Major tournament golf.
Other celebrated names were left to suffer in the sun when the haar that clamped itself to the Wisconsin course, circumstances which forced players to wait, wait and then wait some more, was finally burned off.
For some, the wait was not worth it. Padraig Harrington shot 75, Retief Goosen contributed a 76 and Sergio Garcia posted a 78. On a par-72 course. These are only three examples of figures which will never stand out on such a lavish leaderboard.
Before he began an elongated wait to open his first round at the US PGA, Phil Mickelson could be discovered analysing the state of Whistling Straits. It may not be a Scottish links course, but at times yesterday morning, it must have given off a great impression of one. Long days and unpredictable weather are usually all the rage at The Open.
"What's interesting about Whistling Straits is that it's a Scottish-looking course that plays like an American course," opined Mickelson. "You see the fescues and the sand, the dunes and the pot bunkers and the openings in front, and you think you want to run balls up. But it just doesn't work. It's too soft and the ball stops."
Whatever all the waiting around did for the golfers, it gave one time to ponder the range of adversity weather can dump on such clannish gatherings.
Over three hours of play have been lost in the fog. Probably more than that allotment when one considers the rejigging that must occur to return a sense of decorum to a tournament that will awake early today to complete its second round. It is part of the regular deformities that deface golf.
Weather has devastated nations, and altered the course of history. Golf courses remain par for the course, somewhat simpler to attack than the pins at Whistling Straits.
Russian winters destroyed the ambitions of Napoleon and Hitler, but a severe bout of weather can reduce golfers to rubble. The best laid plans can quickly unravel.
Lee Trevino won half a dozen Majors. He was also jolted by lightning at the Western Open near Chicago in 1975. A time when 'Super Mex' became supercharged. "I thought they would be putting me in the ground on Monday morning," he said.
Woods will never forget his visit to Muirfield for the Open Championship in 2002 when it seemed as if his hands were fighting frostbite during a typical Scottish July.
Nobody will ever hear someone say to Tiger, "Well out" after a bunker shot, but some must have felt like proclaiming such sentiments when he finally left Muirfield. Woods will never forget the third day of that Open, even if he outlasts Jack Nicklaus as the game's most prolific winner.
In the wind and rain, Woods could not even straighten out a brolly. He was condemned to run up an 81.
It disrupted his thought process and ruined his tournament, but it is a familiar plot of havoc which accompanies golf. The fog can depart the US PGA, but mental frailties continue to have a bemusing effect on the minds of golfers.
More dire straits than Whistling ones.
Shots of the day
Paul Casey made his case for the award by chipping in twice in carding a respectable 72, his effort at the fourth hole being particularly memorable. Well in the hunt, and well in luck it seems.
John Daly outfit of the day
Big John may not have set the heather on fire with his opening 76, but he set the standard in trousers with his orange attire and checked trousers managing to give off some vibrant colour amid the early gloom. Mickelson seemed to be rampaging around in gold trousers later on, but we give the award to Daly.
