The first thing to do for a successful class of 1961 reunion is to choose a theme and incorporate it in every detail of the event, from invitations to activities. After that, plan a tour of the school and prepare a list of classmates' addresses.
Invite teachers as honored guests, and pay for their meals, since at reunions teacher-students relationships become more friendly. After choosing the theme, have a casual and intimate welcome night, in a local pub or small restaurant where you hung out during school days, to let memories flood back. Create a website for guests to post photos to from their smartphones. Create a display of photos, awards and memorabilia and place it near the entrance to the main events. Include senior yearbook photos on name tags so that everyone can identify each other.
