When your college president appears to liken the arrival of pandemic disease with the advent of co-education on your campus:

In order to facilitate the physical distancing needed in our classrooms and residences, and to be able to reserve sufficient housing for quarantine or self-isolation in the event of a resurgence of infection, we must reduce the number of students on our campus. Dartmouth has successfully faced this type of challenge before. When we transitioned to coeducation in 1972, President John Kemeny had to determine how to accommodate more students without adding beds. Thus, the D-Plan was born. Now we face the challenge of determining how to accommodate the same number of students with what are, in effect, fewer available beds and classroom space. Today’s situation calls for a new D-Plan.
