Roger and Carol Whitford hosted their annual 9/11 ceremony to honor their son Mark, a New York City fireman who was killed during the terrorist attack. Hundreds of people turned out Sept. 11 for the 20-year-anniversary ceremony. Their memorial is a permanent installation, and the Whitfords said it’s open to the public for when someone wants a moment to reflect. The house is located northwest of Lewes at 17181 Minos Conaway Road.
