November 22, 1993.  Coastguardman Mark Clements washes the windows at the Boston Lighthouse. The Hull coastline is in the background. Boston Light became the last lighthouse in the United States to be automated on April 16, 1998 but a Coast Guard crew continued to perform all the traditional keeper's duties - like washing windows - until September 11, 2001 when the Coast Guard assigned to the island were called to duty after the terrorist attack on America. Since then the lighhouse has been manned by Coast Guard Auxiliary volunteer personnel.
