Just got back from Philadelphia and was able to play both Aronimink and Merion.
Aronimink is so vastly improved from when I last saw it in 1996 - the work then by RTJ and Rulewich was a complete mess of strategy, with no regard for the placement of fairway hazards except to jam up landing areas. Now, Aronimink's fairways require the kind of offset shot-making on drives that makes Seminole so strong, and there's really no more than two shorter layup par-4s, one on each nine (7, 13). Otherwise, you have to work the ball, choose a landing area, and you have to work it left-to-right, right to-left, often followed by an approach into the green that has to bend the other way. That's great design work.
A few other points of observation along the way.
-Kudos not only to Ron Prichard, but also to green chairman Tom Elliott who has been spearheading the work and done much of the in-house politicking. This is by far the hardest and least understood part of all restoration - club politics - and gets not enough attention on this Web site.
-McDonald & Sons' bunkering is so much more interesting than what they did at Merion's. At Aronimink, you can see into the leading edge of the bunker and the back is flashed high, then turfed. At Merion, everything is way too fleshy, too thick-lipped, and way too deep - you have to step down into Merion's bunkers like bath tubs.
-Aronimink has also done a lot of tree work that deserves credit.
-I did think many of the fairway bunkers were way too penal. I'm not sure whether the problem is the vertical depth of their floor, as Prichard seems to be claiming (above), or their relative lack of depth from beginning to end on a south-north axis, so to speak, which leaves little room for the ball to expend energy/momentum as it rolls to a halt and leaves you with too many shots that nestle in under the greenside bunker face, making it impossible to advance the ball more than 20-30 yards. In other words, it might be a design issue, not a construction one. I just don't know.
-I'm a little concerned about the chipping areas. Some of them are intriguing (8th and 10th holes), but at times it's hokey and contrived (back left on 7). Was wondering to what extent these mowed down areas were part of the original plan. It's always hard to do Pinehurst-style chipping areas - the key is making them big enough so that they are substantive, not ornamental. The proper horizontal scale here is crucial.
-The greens at Aronomink are wonderful, varied, and Prichard recaptured many areas behind bunkers that were lost over the years. These are now masterfully done, and the A4 bentgarss is superb, even if a little slow to recover from ballmarks.
-What's with the 122 Slope rating from the back tees? I would have thought this about 12-14 points too low.
As you can tell, I thought Aronimink a wonderful revival. Small wonder it's making its way back up the ratings, and just returned to Golfweek's top-100 Classical ratings, where I think it well belongs. A very strong course. But also playable down the middle from the middle tees for average golfers (like myself).
