Closed Campus

I am unsure of what the reasons are for this decision, but YoungNam SahmYook is now a closed academy campus.  This means that from 8:30am until 5:00pm there is a security guard at the front entrance.  Visitors must get permission to come onto campus.  Staff must wear name tags to identify us.  I am unsure how this will affect off hours and getting back to campus in the evenings when I go shopping.  Might just not leave as often?  Anyrate, not just anyone can come onto campus this year.  It is more protected and secure this way.
