Say this for Donald Trump: the man loves golf, and he loves owning golf clubs. Lots of them. With the recent purchase of Doonbeg in Ireland, the 66-year-old real estate mogul now flies the golden “T” at over 20 courses on 15 sites in the U.S., Puerto Rico, and Europe. Taken together, these facilities form a high-quality mash-up of established properties acquired by Trump as well as a handful of clubs built from scratch by the game’s top designers. Like him or not, The Donald has put his (or other people’s) money where his mouth is.
