Mackinac Island banned automobiles in 1898. In 2200, it has banned everything else. The island sits in the Straits of Mackinac, 5 kilometers from the bridge that connects Michigan's two peninsulas, and it has leveraged its historical no-motor ordinance into something unprecedented in the GLMZ: a technology restriction zone. No motorized vehicles. No neural interface connectivity. No augmentation uplinks. No corporate sovereign territory. No surveillance infrastructure. The island operates under a municipal charter that predates corporate sovereignty law, and the charter's technology restrictions have been upheld by every court that's reviewed them — not because the courts agree with the principle, but because the precedent of overturning a 200-year-old municipal ordinance terrifies the legal establishment.

The result is an island of 600 permanent residents and up to 5,000 visitors at any time, living in conditions that most GLMZ inhabitants would consider medieval. Horse-drawn transport. Paper documents. Face-to-face communication. No data trail. No surveillance record. No jurisdictional tracking. The implications have not been lost on anyone. Ghostbridge Island is the GLMZ's premiere dead-drop location, negotiation venue, and disappearance destination. If you need to have a conversation that no system can record, you have it here. If you need to meet someone without creating a data point, you meet here. If you need to vanish, the island's analog infrastructure means you were never digitally here in the first place.

The Grand Hotel — a Victorian-era structure maintained in deliberately anachronistic condition — serves as the island's primary venue for the negotiations, deals, and betrayals that require total surveillance absence. The hotel's guest list is not recorded digitally. The rooms are not monitored. The staff are hired for discretion, paid in physical currency, and trained in the art of not seeing things. Ghostbridge Island is a loophole in the GLMZ's total information architecture — a place where the panopticon blinks — and every powerful interest in the Great Lakes knows it, uses it, and fears what happens when someone else uses it.
