Gerry B's response on Merion started me thinking about how best to enable courses at multiple-venue clubs to retain their own identity. At Merion, I gather that the west uses the wicker baskets as 'flags' whilst the east (did I get it right) is a shorter course and retains 'flags'. There have been a lot of west/east combinations throughout the world as well as north/south.
Many courses have used the 'Old' and 'New', although how a course such as Walton Heath with construction dates of 1904 (old) and 1906 (new) (did I get this right?) can claim a century old course as new is intriguing.
At St Andrews, the Old/New is combined with Eden/Jubilee etc. At Gleneagles, the King's/Queens's/Princes seems to work well. At Pinehurst, it must be like an old telephone exchange, with Pinehurst #1, Pinehurst #2 etc etc. At Doral, the colours are used but Blue dominates.
More recently, the St Andrews Beach golfing venue near melbourne has 2 courses underway with names of their own. Gunnamatta and Fingal. So, perhaps they will retain more of their own identity than as 'St Andrews Beach #1 and St Andrews Beach #2'.
What examples are you aware of to promote the interest in each course at multiple site venues so that one course does not dominate easily over another, and to ensure that each course is recognised for its own character?
