He was part of the greatest day of my life golfwise. I was set to play golf with Rick Barry, the president of the company that was trying to win my business, and a teenage Tiger Woods at Lake Merced GC in SF. Willie showed up and wanted to play with us. After a bit of talking, Tiger dropped out to play in the group behind us and Willie joined us.
Tiger was only 16 at the time, but already semi-famous. He was visiting Stanford and playing Lake Merced in a practice round for some future event. Every hole, we would hit our shots and stand to the side and watch Tiger drive. I was a long hitter. Rick Barry was longer than me. Tiger was way longer than either of us. It was very impressive.
Willie was the nicest man. Rick Barry tried to talk him into doing autograph sessions where he got paid for each signature. Willie said that he would never, ever charge for his signature. As far as I know, he never did.
