Belle Isle

South of the United States, and North of Canada, lies Belle Isle.
Well, it's not really South of the United States, since it's part of Michigan. But one developer wants to change all that and turn Belle Isle into a charter city, a "free market utopia".
Somehow I don't think this will happen:

Private investors buy the island from a near-bankrupt Detroit for $1 billion. It then would secede from Michigan to become a semi-independent commonwealth like Puerto Rico and the Northern Mariana Islands.

I don't think it could "secede". But... I believe Michigan could "cede" the island to the Federal government. Yes, states in the past have ceded land to the Federal government.

It's an island dream
and a wild scheme
and it doesn't seem
very likely.
