Twenty five years after the storm, Charleston Mayor Joseph P. Riley Jr., the longest-serving mayor in Charleston history, says preparing for and recovering from the storm was the most important time in his service to the city. Sunday, Sept. 21, 2014 is the 25th anniversary of Hugo's landfall. (AP Photo/Lou Krasky, File)
