I enjoy the course and the town and I feel ready to go. Sometimes just driving in the front gate of a place will get you motivated, even if you have not been playing well.
I think last year and 2004 when I won, I was playing particularly well. Today was one of those rounds where I played particularly well again. But it does help when you come back, no doubt. Horses for courses, isn't that what they say?
I feel like I've been playing well, and being back at Oak Hills should put me in a good frame of mind.
