The ferry crossed the Matanzas River again Tuesday afternoon, resuming service nearly nine months after Hurricane Matthew toppled trees and battered docks and boardwalks. This was hardly the first time nature has altered these pieces of sand. And it certainly won’t be the last. When I set out to visit each of our local national parks this year — using the National Park Service beginning its second century as my excuse — I didn’t plan to make Fort Matanzas National Monument one of the last stories. But maybe it’s fitting.
