I don't know about Bedminster, but Doral was 1 of the worst tour venues on an annual basis, and I'm glad they left it. The best course he owns is Turnberry, which is 1 of the best Open venues, and I always wondered why it's the least played venue.
It's one of the least played venues recently because the R&A has basically said they are not going back as long as it is under Trump ownership. So 2009 might be the last time we see an Open there for quite a while.
