North Shore Squares is a new club that dances in Evanston, ILL. Despite only being active for 18 months or so they already boast 55 members. They elected to use the Sustainable Square Dance (SSD) lesson system (previously known as Club 50) to facilitate rapid intakes of new dancers combined with retention after graduation from lessons. As a teaching aid they prepared booklets containing a concise and easily read definition for each call, many including color diagrams to illustrate the action. The first booklet contains calls on the SSD list. The second contains the MS calls not on the SSD list and the Plus calls.
