Horry County hosted a public safety exercise Saturday.
It took place around the Bucksport Marina in Horry County, Sandy Island, and the Wacca Wache Marina in Georgetown County.
Horry County's Emergency Management Director says the drill is vital. "One of the big issues and why we do these things is communication with each other all the different agencies and organizations that are involved. We don't always respond together on things but communication is one of the big things that we try to make sure we can do," said Randall Webster.
The exercise lasted two hours.
Large numbers of first responders and military vehicles participated in the drill.
