My father, Verle Kins, was a Rotarian by spirit and by his profession of facilitating the growth and development of youth (and the leaders who volunteered) through the Boy Scouts, Girl Scouts, and YMCA. We moved every 4 or 5 years. And every time we moved to a new location, Verle would transfer his Rotary membership to the new Rotary club location. His advice on membership was to identify the new leadership in your community and invite the new leader to attend or participate in a club project that had personal meaning to that person.
Verle also suggested that each Rotary member set a goal of inviting a guest each quarter. They could simply attend or be the program for a meeting. This way the person could identify how the club programs and projects dovetailed with their vocation. They could see how joining the club could assist them in achieving their goals.
