I played Congressional late last week, and although I didn't take any pictures, I thought I would pass along a few of the setup and design changes that were most noticeable to me.
1. In most places, the first cut of rough now extends to (and often around) the sand traps. It's now much easier to have a drive scoot into one. Consistent with other recent setups, there is also an intermediate cut (in between the first cut and the longer rough) of about 7-10 yards wide.
2. On a couple of holes, the fairway has been shifted to one side or the other, so that it's closer to the fairway bunkers. This is particularly noticeable on #3. They've eliminated some lame mounds in between #3 and #4. They yanked the fairway bunkers on #11 that were in between the fairway and the hazard. And they've cut a narrow swath of first cut down the hill on #16 [which used to be all rough], perhaps leading some players to try to bomb it down the hill.
3. In what I think will be the change most criticized by the players, the entire right and back side of the par five 16th green is now mowed to fairway height, as a result of which misses will roll down into pine straw, under trees with some relatively low branches, well below the green. The green site is nowhere near as severe as #14 at Pebble, but I predict that some guys will criticize the change as unfair.
4. When they redid the greens, they grassed them with (I'm told) a creeping bentgrass hybrid called C-19. Apparently this grass is somewhat more resistant to the heat, but it has a decent amount of grain. I got completely fooled on a long downhill putt on the 3rd hole, which I left about 15 feet short because it was into the grain. I don't think the greens were rolled the day I played, but there's still the chance of their getting a little bumpy. They were, however, quite firm.
5. I can't prove this, but some of the greenside traps seemed deeper than before, and the sand also seemed softer.
6. Some of the new tees seem like they're in another universe. We played it from 6800 and there are tees you can barely see from there. They're also contemplating having #12 play from one of the tees on #15.
I probably noticed a few other things, but can't recall them now.
