US to give away free lighthouses as GPS makes them unnecessary

Program aims to preserve the properties, most of which are more than a century old, to anyone willing to preserve them

Ten lighthouses that for generations have stood like sentinels along America's shorelines protecting mariners from peril and guiding them to safety are being given away at no cost or sold at auction by the federal government.

The aim of the program run by the General Services Administration is to preserve the properties, most of which are more than a century old.
