CHARLESTON – Dodging flooded streets, gusting winds, which prompted a tornado warning, and stinging rain, postman Gregory Marsh and other United States Postal workers continue to deliver the mail, despite the elements.

“I mean it’s my job,” Marsh said while sporting his USPS slicker and wide-brimmed hat. “For some other hurricanes, yea I was out here. It’s not bad right now. It’s just a little windy. We can’t go through the flooding water. We just do what we can and bring it back tomorrow.”

Marsh scanned a package and then rapped on Jeff Carpenter’s door to let him know of a package.

“Thank  you, very much,” Carpenter told Marsh from his side porch.

“Have a great day and be safe,” Marsh replied.

“They’re right, neither rain nor snow, here you are out here in it,” Carpenter said, quoting part of the USPS creed.
