Abstract

The author had the honour to organize and shepherd the meetings of C 3 S 2 E and IDEAS. The former went through transformations from Canadian to international meetings! This year is the silver anniversary of the latter. It has been an exciting quarter century to organize and hold these meetings and publish their proceedings: through good times and not so good ones. During this time we survived Ebola, MERS and SARS. Whereas the others were local, the Covid pandemic, which still rages, has forced us to move to an on-line version, but thanks to the participants and the dedicated program committee we have continued. This paper is a photographic journey through these years. Unfortunately we have not been able to have the images of all participants over the quarter century, just a sampling of some of the fond moments during the social gatherings of the IDEAS/C 3 S 2 E
