CLEMSON, S.C. (AP) -- Playing can be serious business.
Starting Sunday, Clemson is hosting a conference put on by the U.S. Play Coalition.
Organizers say the conference fosters discussions on the value of children's play by bringing together people from fields including education, medicine and psychology.
Dr. Michael Suk, an orthopedic surgeon at Geisinger Health System in Danville, Pa., is giving a keynote address. The conference runs through Wednesday.
