Just an aside, and an FYI - I spent almost an hour today on youtube watching an old Shell Wonderful World of Golf -- from 1962, it was a match at Pine Valley between Byron Nelson and Gene Littler. Only the introduction and first hole were not available; otherwise we get to watch 17 holes (in 10 minutes segments), and they do a very good job of highlighting the design. Byron finished +2 and Gene +6 or +7 and it was a pleasure to watch in so many ways. But also, what an eye opener -- both golfers used driver on the Par 3 5th, for example, and to watch them approaching some of the greens with 3 or 4 irons (or recovering with usually nothing more lofted than a PW) was striking. (They also played FAST). Anyway, that was my main point -- to give a heads up in case you didn't know it was available for viewing. But secondarily: it strikes me that there is NO WAY that even a tough championship test like Doral (in 2015) was as challenging as Pine Valley was in 1962.
