The fate of the American nation was once inexorbly tied to the sea, and nowhere is its maritime tradition more evident than in the lighthouses that line its coastlines and Great Lakes. Even as sophisticated sonar and satelite technology has rendered their powerful beacons and errie fog signals superfluous to giant oceangoing vessels, lighthouses still project comfort, safe haven, and nostalgia to small boaters and millions of visitors. Impervious to terrible storms, towering majestically above bustling harbors and vast coastal marshes, these great beacons embody the resourceful spirit of generation of lonely keepers and their families.
