Tim - now you're getting technical. Remember, by all public records, "The Institute" does not really exist.
But that being said, I have confidence I will play that some day... either they'll finally ask for an NCGA rating (in which case I'd have a very good chance to be on the team doing it), or I'll get some other invite. I do know a few people who've played it already.
I have zero faith I'll ever play Augusta, and I know maybe 2 people outside of this site who have done so.
In any case, the exclusivity or hard to get on factor is really not the driving issue here, not for me anyway. For me it's all about the Masters and reliving those shots.
