Some places don't care. I much prefer those places.
Last (first) I played Muirfield was in 1980, and I think I paid 10 Pounds, having written months before hand. After golf and lunch I went over to the offices of the club secretary, the legendary Capt. P.W.T. Hamner, Ret., and asked (it was a quiet Tuesday afternoon) if I might be allowed the honor of walking the course. He went immediately to the files, produced my letter and the accompanying letter of introduction from my mentor, and thundered, "There's nothing in here about an afternoon walk. I'm sorry, but no, we can't allow it." And that was that. Very humbling. It was their course, his course, and that was that.
