practice your golf swing on a nice little executive course.
I was a golfer in high school, but hadn't picked up clubs in seven years. But the Golden Gate Park Golf Course was a great little course to pick up clubs and just go for it.
The full 18 holes took us less than three hours to complete. Didn't bring your clubs? Not a problem. The course has clubs for rent. No golf attire? Casual dress is perfectly fine.
