Only one other time has a PGA Tour leader board been this crowded after an opening round.
Eight golfers shot 5-under 65s yesterday and were tied for the lead at the U.S. Bank Championship in Milwaukee.
Another 10 golfers were one shot back.
"A lot of people, a lot of golf [left]," said Danny Briggs, who was tied for first with Todd Fischer, Bo Van Pelt, Brett Quigley, Patrick Sheehan, Brian Kortan, Robert Gamez and Olin Browne.
The Honda Classic in 2000 had the only other eight-way tie for first after one round, according to the PGA Tour, which began keeping such statistics in 1970.
The crowds seemed a bit sparse -- many fans might be following the lead of some corporate sponsors and saving their money for next month's PGA Championship at nearby Whistling Straits.
But the field is a little deeper this year, and the course at Brown Deer Park is beefed up, as well. The greens are firmer than normal and the notoriously deep rough is nastier than ever.
"Last year I remember the rough being up here, too," Fischer said. "But there's some spots here that you might need a Weed Eater to get out."
Among those at 66 were Paul Azinger, who called this "a mini-U.S. Open," and Jerry Kelly, who described it best when he said the rough he encountered on No. 15 was "a bird's nest in a hawk's nest."
* EVIAN MASTERS: Karen Stupples shot a 6-under 66 to take a one-shot lead over Laura Davies and Annika Sorenstam after the second round in Evian, France.
Stupples is at 10 under overall following a round that included seven birdies and just one bogey.
"That was all-around enjoyable," said Stupples, who will be paired with Sorenstam today. "But I must admit I'm a bit surprised to find myself leading."
Sorenstam finished with a 69 while Davies, the leader after the first round, eagled the 18th hole for a 71.
Davies bogeyed four of the first five holes, before getting birdies on the seventh and ninth holes.
"Frankly, I considered heading for the beer tent," she said of her early struggles.
* SENIOR BRITISH OPEN: Eduardo Romero opened his seniors career with a 5-under 69 and shared the first-round lead in Portrush, Northern Ireland.
Romero, who turned 50 five days ago to qualify for his first seniors event, birdied three of the five par 5s at the Royal Portrush links. But the Argentine also had two bogeys.
Don Pooley, John Chillas of Scotland and Jim Rhodes also had 69s, with defending champion Tom Watson six strokes back at 75 despite an eagle on the second hole.
