At most public courses in my area (Michigan) weekly leagues are formed Mon-Fri and last 16-20 weeks (May-Sept). Individual leagues may have as few as 16, and as many as 50+ players. Some leagues are individual play, while others are two man teams. It's usually handicapped play with your handicap being determined by your first few weekly scores. Competiton can be very keen, or very casual, depending on the make-up of the group. Here, league play differs from club play, in that anyone can play in a public course golf league without having to become a member. somewhere.
