Uncle Sam is selling the tiny island east of New York City.
The government has used the island for a research station on dangerous animal diseases since the 1950s.
One local real estate expert says development of the island could be worth tens of millions of dollars.
But before the island goes to the highest bidder, the town of Southold wants to have a say.
Officials are proposing to create a conservation zone covering much of the 843-acre island.
