The United States Lighthouse Society offers lighthouse aficionados the ability to track and map which lighthouses they have traveled to see. The Friends of Borden Flats Lighthouse holds the stamps for Borden Flats Lighthouse.
Copies of the stamp are available at the Borden Light Marina office from May 1st - Nov 1st. Please check their site for hours and please avoid calling their office, as they are offering this service as a favor to the lighthouse community. If you're in the area and are not able to stop in and receive your stamp, we are happy to send one through the mail, just send us a quick email - firstname.lastname@example.org
