Tim, I presume he was sampling Scottish golf. I played with a group of members there in October who told me about it - I think the members appreciate that their course can no longer stand up to technology.
Adrian, I might be wrong but there just isn't room at Prestwick for an Open - even if the course was long enough, where do the tented villages, media centre, corporate tents etc go? I also think its a club which is quite content in being what it is today - the added attention might not sit so comfortably.
Phil, the Himalayas hole is a blind par-3 over the hill - not even the most ardent admirer of Prestwick would suggest that one should strive to copy it!
