Have you ever wondered why it is/was so dark on Hilton Head Island ?
The Town of Hilton Head Island requires that lights on structures visible from
the beach be shielded or turned off after 10 PM from May 1 to October 31.
Any windows facing the beach must also be covered with draperies or shade screens.
Lights out for the Turtles
