Carl:
From what I've watched (big caveat -- never been there in person) over the years, Augusta National seems to be full of false fronts. The 9th is the one that probably comes to mind immediately, but don't others there have the feature as well? I was thinking of 10, 15, and one of the par 3s on the front nine.
Also, re. your point on consensus -- it seems that some like subtle false fronts, ala what Tom described in his first post. The big bold ones -- both of the ones I pulled from Milwaukee are really quite large and dramatic -- seem to generate a wider range of opinion. Milwaukee may have a few other modest false fronts, but those two are the ones you notice right away, and are much more prominent than anything else you find on the course. Given that they are on the two shortest par 4s on the course, and players often have wedges in hand on the approaches, I think they work.
Ed -- thanks for the pics!
