PARAMUS, N.J. -- Hale Irwin was a little surprised Monday when the locker room attendant at the Ridgewood Country Club told him he had been there about 15 years ago. Irwin didn't recall the visit. In some ways it's not surprising. When you're a professional golfer you play at a lot of courses and one or two might slip your mind. That's not happening on Irwin's visit to Ridgewood this week. He is trying learn everything he can about the A.W. Tillinghast-designed course, which will be the site of the 62nd PGA Seniors' Championship, starting Thursday.
