North Berwick (West Links) in 1975 because I knew next nothing about GCA and hadn't heard about the course. The golf tour company set up the arrangements. (Troon, Prestwick, Gleneagles, Blairgowrie, TOC, Carnoustie, EB-WL and Gullane #1). Very few golf books.
Edit 8/17: Before the turn of the century I got internet access and a bunch of books (Doak, Steel, Finegan et al.) and even since I've had some reasonable expectations before I decide where to play. The top suprise was Juniper in Redmond, OR (Harbottle) after it moved across the airport. Santa Anita and Soule Park, Jasper and Pine Needles are honorable mention.
