Joe, but Medinah has 3 courses. I don't know the answer for sure, but would guess that they have flights or even seperate club championships for each course, the women's, the middle regular members, and the championship #3 course.
Isn't this just the very problem with designing these modern courses with tees beyond 7000-7100 that only the top 1% realistically can play on at those distances? Why should a club, with a vast array of members, cater to the 1% when it comes to club championships of a membership that probably has an average club wide handicap of >10?
Some courses like Medinah revel in their brute length and demanding narrow accuracy. That is fine, and that is the kind of top player members they should draw. But, if one is marketing a golf club under normal player population circumstances, why build or maintain a course at 7000+ and have competitions at those lengths where 99% of players don't belong, unless that is your target market of top 1% players?
Clint, we only set the tees at the tips for championship flights, and don't build further back tees, because they aren't needed. We could, but why? It is tough enough and ID's good players now as it is as a proven fact. If we had 7100+ tees, what would that get us; a much smaller flight that could play back there and yet still not beat par that they aren't doing at 6750?
