United States Lighthouse Society Passport
The United States Lighthouse Society sponsors a Passport Program. A passport with a blue vinyl cover, similar in appearance to an official United States passport, is available through the Sodus Bay Lighthouse Museum and at other lighthouses across the U.S.
When you visit a participating lighthouse, you can get your passport stamped. There are four panels on each page of the passport and each panel should have a different lighthouse stamp. When your passport is filled it will contain 60 stamps, and you may send it to the United States Lighthouse Society to receive a specially designed lighthouse patch.
