I'm surprised that a discussion of blind holes doesn't include a reference to Tobacco Road. By my count there are as many as 7 holes with one or more blind shots (1, 2, 7, 13, 15, 16, 18).
In my opinion, Hole #18 has one each of the "good" and "bad" blind shots. An aiming "post" is provided on the drive and its clear from the yardage book that the fairway is quite accommodating, so I guess I'd consider this a "good" blind shot. The approach, however, can be blind from a majority of the fairway. I had to walk from the center of the fairway, up a slope on the right to see where the pin was, and from there I could not see that there were several huge punchbowls surrounding the green. I would have been a wee bit upset if I would have hit a shot that I thought was decent, only to find myself in a 6' deep punchbowl. I would consider this a "bad" blind shot.
Lest you think I only like easy blind shots, I very much enjoyed the blind approach to Hole #13.
In thinking back to The Road I don't think there are as many blind shots as you suggest.
#1 is certainly blind for the tee shot and the second (or third depending on how one plays it). However, the drive being blind is of little consequence. The second being blind makes a huge difference though.
#2 is blind if one takes the conservative drive out to the left. An aggressive drive to the right offers a view of the green. This is what I think of as an example as an excellent risk/reward concerning blindness. However, I wouldn't call the hole blind if there is an option to see the green.
#7 is blind, but it doesn't make a lick of difference.
#13 can be blind off the tee for those aggressive enough to go over the trees on the right. Again, a safe and very visible option is offered straight away. The second is either a blind layup or for the flat bellies a blind approach. Sometimes the flag can be seen. I would say both the layup and the approach are effected by the blindness. Cleverly, I think the much more important issue for the approach is the raised green. The blindness probably puts people off, but the real issue is to take enough club because so many come up short here.
#15 offers a blind drive for the aggressive and a straight forward layup in sight. Again, I wouldn't label this a blind hole because there is a choice. If the layup is well placed with the pin on the right it can be seen. I am not sure if the pin can be seen if its far left from anywhere in the fairway unless a guy bombs it down left of the 16th tee. Its certainly doable for flat bellies. I encouraged Big Ed Galbavy to do just this, but he understandably had the jitters about doing this.
#16 tee shot is blind, but like the approach to #13, the important aspect is not the blindness, but taking enough club to leave oneself a straight away uphill approach. There is plenty of room for the layup drive so I think blindness is of little consequence.
#18 is blind off the tee, but its really a matter of smacking a good straight drive - the blindness isn't an issue - the penal nature of the shot is much more the issue. I don't mind it though because all good courses need to have some shots which REQUIRE something of the player - meaning, there is no option, do as you are told or suffer. The approach is normally blind unless one hits a cracking drive and in the perfect spot. Like you, I was a bit perplexed at finding my first approach left when I though I hit it perfectly. Its a bit of a nasty blind approach because its tough and I am not sure it works. This is the only blind shot on the course I would question and they may be mostly down to it being the last hole. I think it would work better if this hole came earlier in the round - it gives one a chance to wash out the bad taste this hole can leave.
So, I don't think blindness is nearly as much an issue at TR as a cursary glance may suggest. In this way I think Strantz was extremely clever. There is so much to admire about The Road that I think all golfers should see the course at least a few times.
