The Class of 73 (COST) Cohort includes the 104 new entries to RMC in and around January 1970 and the 25 others who joined then along the way, albeit briefly in some cases, and would have, should have, could have or surprisingly for some, actually graduated in December 1973.

The COST Cohort also welcomes the inclusion of close relatives and friends who want to share memories and news as time passes.
