FWIW - my take on a few of these courses, and a few not yet mentioned.
As background, I'm pretty much a public course hacker. I've played all of one private course in the central Indiana area in the 23 years I've lived here, so my comparisons can't include the likes of Crooked Stick, Wolf Run, Broadmoor, et al.
To start with, my most recent round. Happened to be this morning, at Plum Creek, which I had never played before, despite living about a mile away from the course. Actually, I live across the street from the Brookshire clubhouse, which is an early 70's Bill Diddel design. Plum Creek was much more enjoyable than I expected. It doesn't look like much from the adjoining roads, being pretty flat, so I wasn't prepared for the nice job Liddy/Dye did with shaping the fairways and green complexes. It struck me as a pretty good course to use to show someone who doesn't know what is a "Liddy/Dye course"? Generous fairways, if you play them safe, but enough risk/reward offered to make it interesting if your driver is working. The major comlplaint I hear about this course from people I hang out with is that it's overpriced. I'd agree, in light of the abundance of courses in the area.
Eagle Creek was, indeed, dissected and reanimated in new form a few years ago. The "old" EC had a very distinctive feel and layout, and the new holes that were added suffered more from not having the same look as the old ones than from lack of innate quality. The new holes were located on flat, treeless farmland, which was quite different than the heavily wooded and tree-laden originals. As time goes on I expect the holes to be more accepted. Conditioning at EC has been hit-or-miss for a long time, as it has at another nice Indy muni:
Coffin If the grounds crew could get (and keep) Coffin in reasonable shape, this would, IMHO, be hands-down one of the best values in central Indy golf. A Liddy course. Tim, your course deserves better.
Pebblebrook - South yawwwwn...Sorry, perhaps the most boring routing in Hamilton County. Haven't played the North course, I hope it's more invigorating.
West Chase. Greatly underrated. Very nice combo of long and short par 4s, a few big elevation changes, and some tricky greens. Me likey.
Bear Slide. I've yet to hear a single person say they don't like this one. Someone mentioned the 18th hole - yep, it's a nice finisher. Like West Chase, a good combo of long and short holes, #15 is perhaps my favorite short par 4 in the area. I really like the routing, it covers all points of the compass.
Sahm. A very early Pete Dye muni. Compared to its peers in the Indy muni system (Riverside, South Grove, Pleasant Run) this is quite a cut above. The layout is certainly much more interesting and visually intimidating than you might expect for a $16/round course.
Well, I could go on, but that's plenty for now. Have yet to play Purgatory, Trophy Club, Rock Hollow and Prairie View. Maybe next year....
