In 1998 time and Senator Kennedy reached a compromise: the light itself was at last automated, but it remains the last one with resident Coast Guard keepers.The Coast Guard took charge of America's more than 1,000 lighthouses in 1939, when it absorbed the United States Lighthouse Service.
Since then the federal government has moved 84 lighthouses of the 600 that were left off its books.

People are often quite surprised to find that what they're using, what they're doing, what they're seeing, is actually New Zealand product.Can you give some examples?The one I really love is solar-powered lighthouses.
