Thousands of Americans are still stranded in Mexico days after Hurricane Wilma left the Yucatan Peninsula in ruins. Charles and Tiffany Kiefer of Durham have been stranded at a shelter for the past four days. Family members, including Charles parents, who live in Beaufort worry that the couple has been left there to fend for themselves. The Kiefers have no idea how long they will remain in Mexico. Continental Airlines, as well as airlines from other countries, picked up their passengers who were ticketed to fly with them.
