There's a huge fence around the course to keep out animals. There has been one deer sighting in the last 65 years.

TV commentators are not allowed to refer to fans as "fans" or "spectators." They are to be called "patrons," and the rough is to be referred to as the "second cut."

The Masters banned CBS broadcaster Gary McCord in 1995 for saying, "They don't cut the greens here at Augusta, they use bikini wax."

Players are allowed to use their own caddies now, but they have to wear the Augusta uniform — green hat, white jumpsuit.
Like many golf courses, there is good fishing at Augusta National, but the players don't like to talk about it because it is forbidden.
In 2011, Monte Burke of Forbes interviewed golfers about the best fishing spots on the PGA Tour. When Augusta was brought up, he described their responses as "squeamish" and only admitted to hearing there were some good spots.
A former caddie was willing to tell Burke that the best spots are the creek in front of the 12th hole ("full of bream"; seen above) and the pond at the 16th hole ("brimming with bass").
Patrons can bring collapsible chairs to sit on, but those chairs are not allowed to have armrests.

There is an odd myth that the grounds crew at Augusta packs the azalea plants with ice if spring comes early. The idea is that this will keep the plants from flowering too soon before the tournament.
There is a house located in the middle of the Augusta National parking lot because the owners refuse to sell it. The family has reportedly turned down "millions."

Players are given brand new Mercedes for use during the week.
Golf cart drivers who are hired to drive the players around Augusta National also pick up the golfers at the airport in the Mercedes they will be using. The cars also have a number in the back window so that employees can always identify the players by which car they are in.
You can go to jail for selling tickets.
Twenty-four people were arrested outside Augusta in 2012 for trying to scalp tickets.
The course is insane about who it lets into the tournament and it's illegal to sell tickets within 2,700 feet of the gates.
You can only ask for autographs in one part of the course.
Fans always line the ropes at big tournaments in hopes of getting a signature. But this is tougher to do at Augusta.
You can only try and solicit an autograph on the Washington Road side of the clubhouse, near the practice facilities.
The bunkers at Augusta are filled with mining waste.
You know those pristine white bunkers?
They're actually composed of waste product from the mining of aluminum, according to Golf.com
Basically, there's this company that mines feldspar (rocks) for aluminum. This process produces waste in the form of really bright, pure quartz — that's what Augusta uses.
Augusta opened a new media center this year and it is gorgeous.
That new Augusta National media center tho...
Wow. See you soon. #Masters pic.twitter.com/BjzPYNMejf

The course used cows as lawnmowers in the 1940s.
Augusta is its own universe with a tenuous connection to the outside world (see: all the ridiculous anecdotes in this slideshow).
But WWII affected Augusta just like it did the rest of the country. During the war, Augusta didn't have the manpower to maintain the course, so they set 200 cattle loose on the grounds in hopes that they would "trim" the grass by eating it.
