Augusta, Ga.
Charley Hoffman, who has one PGA Tour victory since 2010, took the early lead at the 2015 Masters with a 67. He eagled the 15th and shot 33 on the back nine. At the moment, Justin Rose is on the 17th hole and also is at five-under.
The last seven years, the winner of The Masters opened with a score in the 60s.
You can follow leaderboards elsewhere, so I'll offer personal observations from the course: It's packed. It's packed in places I haven't seen it packed before, and even around less-popular groups. I've never seen such a mob scene at Amen Corner.
It's difficult to see the more popular groups, at least from up close.
It's also stunning how quiet and still these large crowds can become when a player approaches the ball.
When you cover other majors, marshalls are constantly raising their arms and shushing the crowd. Here, the crowd quiets by itself.
There are some tough pin placements out there - on the ridge at No. 4, back right at No. 6, back left at 10, straight over the bunker on No. 12.
