The Decatur 600 Club is open to all Decatur USBC WBA members who have bowled a scratch 600 series in sanctioned play and have paid local dues of $3.00 per year.

In January the club conducts a Doubles/Singles tournament. Doubles and Singles are available on each squad. You may bowl both events back-to-back, or, bowl each event on separate days. Members are encouraged to bowl both events; however, bowling in only one event is acceptable. The tournament is a handicap event. Prize money is returned 100%, with at least one prize for each 3 entries. Participants may bowl only once in each event.

The annual meeting of the club is held on Sunday (last date of tournament) between the 1st and 2nd squads.
