Tom,
I didn't say that interrupted fairways were planned only for topped or poorly hit shots. I saw no need to add to what Tom Paul and Mark Fine submitted.
If you ever visit Rolling Green, you will come to discover that the ground leading up the stream and the narrowness of the stream make topping a shot over the stream a very likely occurrence from various distances from the stream. What explanation do you have for the second fairway starting 30 yards or more beyond the stream? The second fairway begins a mere 110 yards from the landing area indicated on the drawing. In your consideration, you wouldn't know it from a drawing, the tee shot is some 80' above the landing area.
I could post many more drawings showing the use of interrupted fairways. I posted the ones I did for a reason, even if it escapes you. Craig discussed the 5th at Manor, so it was posted for that reason. The 7th at Rolling Green is an excellent example with the distances related to the line of play, which is why I posted it. Bill Dow asked about the 7th at Kittansett, so I posted that. As you can see, I posted three drawings, not two. The third drawing of the 7th at Kittansett has no stream. So it isn't that interesting at all, unless you choose to make it interesting.
Go over to Mike Hurdzan's office and take a look at hundreds of other examples where there are no streams. Let's hear your interpretation. You've seen a few Flynn courses including the Cascades. You should be familiar enough with the 2nd and 5th holes to surmise why those two were planned with interrupted fairways, and have them once again.
You may have missed one of my points. Why do you think some architects start fairways at different distances from the tee? Specifically, why do you think some classic era architects did it? What explanations do you have for Flynn designing that way?
