US Coast Guard's last lighthouse keeper looks to 300-year milestone

A singular lighthouse and its unique keeper are celebrating a milestone.

Boston Light, the nation's first and oldest lighthouse station, turns 300 on Sept 14. Sally Snowman, the Coast Guard's last resident keeper, is helping with celebrations.

Events are planned for downtown Boston's waterfront and other parts of mainland Massachusetts. The lighthouse's beam - visible for 27 miles - will even be ceremonially relighted at sunset.
