Have you ever thought that your weekend golf course was difficult? If you said yes, then there's something wrong with you, you're lying, or you're just that bad.
If you want a hard test, I can give you one.
Just step out onto any of the courses in the next 25 slides, and tell me your score. All of these courses have or would give Tiger Woods and the rest of the PGA a good battle (one course actually demoralized the players).
