The are by Definition, Immovable Obstructions. It needs a declaration by the Committee to make them an IPC
From England Golf:
4. Immovable Obstructions (Rule 24–2) include: a) All artificially surfaced roads and paths on the course, including those covered with wood chips. All other paths and tracks are integral parts of the course. b) White lined areas adjoining any immovable obstruction are part of the obstruction and not ground under repair. c) Stone-filled drainage ditches or channels. d) Sleepers, steps or wooden boards within bunkers.
Played a round at Pebble Beach and Muirfield Village on the simulator last weekend. Low winds and gimme on the green. Shot +2 and +1. Even assuming I add on another 14 to 16 strokes, am happy to have played bogey golf on those courses. Was beaming the rest of the day post that
He played Nike gear right up until they announced they were getting out of the golf equipment business.

Matsuyama, Spieth and DJ all winning in consecutive weeks is creating a lot of drama heading into the Masters, not to mention Justin Thomas emerging as a contender with his terrific play. Already three wins for Thomas in the wrap-around 2017 season!
You have to consider those four the big favourites....though there's also McIlroy going for the career grand slam, Day looking to contend again (though this could be a 'lost to swing changes' kind of year for him), Fowler looking to break through with a major, plus old standbys like Mickelson or Westwood likely to be buzzing around the leaderboard again. Maybe we'll see Langer turn some heads again, or Couples once again be in the mix heading into the weekend.
In short, this is promising to be a terrific Masters, even if/when Tiger has to WD again.
