I last played Bretton Woods about 9 years ago and it was quite underwhelming: the holes were pretty boring (many very very flat without any real interest) and the conditioning was terrible-- wet, slow, bad grass, etc. The holes closest to the Potomac were the worst, since they were the wettest and flattest (and most bug infested).
I hadn't realized that they were undertaking the work described by Rob, which sounds great. Since everyone I know who belongs is a non-golfer, I just assumed the club (which has a heavy World Bank/IMF membership) was fine with it the way it was.
