Why are Royal Portrush and Royal County Down "unsuitable"?
I was told by several people who claimed to have witnessed it, that Tiger went around the front 9 at RCD in "about 45". Mind you, he was out for fun, not holing everything out. If the wind were up, and Tiger was playing around on a course he never saw before, why would he not make bogies? I once saw him make a triple bogey during competition.
They were from Northern Ireland, these people, and of course I'll allow for the possibility they were exagerrating the difficulty of their course. You believe whatever you like, but I think RCD would host an entertaining Open.
