Jim,
We played Yale last summer as I am sure Paul told you. Just gets better and better. Don't recall any problems with the bunkers on 5 (Short).
Aside from drainage, the biggest improvements were:
1. Cutting the high grass on the banks (eg left greenside on
so that the ball can be found and runs to where it's supposed to, in the case of 8, the bunker; and
2. The removal of trees which has changed the whole visual dimension of the place. With all that fescue, most of which is out of play, and the rolling nature of the property, it's beautiful to look at from all sorts of angles.
If you come East in May you are invited to WCC.
See you in North Carolina.
