(WMBF) - As the deadline to register for the Horry County Schoolsâ virtual program nears, Gov. Henry McMaster is starting a push to make masks optional for students inside South Carolina classrooms. âI think it is a height of ridiculosity for a school district to make that decision for the parents, particularly since we know that even when the virus was rampant that the schools, the classrooms were the safest places of all,â McMaster stated.
