Eastport, Maine is near Campobello Island where FDR spent many summers and where he was well aware of the exceptional tides. An engineer by the name of Dexter Cooper planned to harness the tides to generate electricity and he had FDR's support for what became known as the Quoddy Dam Project. This was a huge public works project and the work, budgeted at $36,000,000, was begun in 1935 although Congress ended the project the following year. Eastport still has a room sized working (in summer) scale model of the project that was constructed in the 1930s. A very limited issue F.D.R. related button. NM displaying Mint.
