Picking a nit here,
MUSC is in Charleston.
USC Medical School is in Columbia, about -6-7 miles away from the main campus, on the eastern side of the city.
The Arnold School of Public Health is located on the western side of the main Campus of The USC, not part of the USC Medical School.
I work at USC and was locked down for a bit over an hour, broke it here: Shots fired at the University of South Carolina (Situation Over, update at #32).
Do the students “swap out”—have tele-con classes at both campuses, and share administration resources? Certainly the two places have individual identities. But I take your point.
