I played the Old Course twice, many years ago. Loved every minute of it, but here what I took away:
If I didn't know it was the home of golf, if I didn't know all its history and I went on a golfing trip to Scotland and Ireland for a month, and they put me on each course blindfolded, what would I think of the Old Course?
For starters, if I didn't have a wonderful caddy and my "A" game the first time I played it, I would have been lost.
Second, #1 and #17 would clearly be stupid holes that any architect would get critized about. I like 18 as a tournment finisher, but seems to be a let up hole that properly belongs about 12 or 13 before turning for home.
I don't really have any desire to return and play the Old Course before playing the North and East of Ireland Courses and Kingsbarns.
On the other hand, considering that this course was built 500 years ago, and it is so challenging, it is pure genius.
