Kenosha sits on the state line between Illinois and Wisconsin, which used to be an administrative boundary and is now a jurisdictional fracture. The Illinois side falls under GLMZ's corporate sovereignty framework — Axiom jurisdiction, tiered citizenship, surveillance infrastructure, the whole apparatus. The Wisconsin side falls under the Milwaukee Administrative Zone's separate charter — different corponation alignments, different tier definitions, different laws about what you can do with a neural interface and who owns the data it generates. Cross the state line and your legal identity changes. Your tier might change. Your insurance definitely changes. The corps that have jurisdiction over your augments change, which means the firmware updates you receive change, which means your cognitive baseline changes. Kenosha is where you feel the seams of the system, because the system was never designed to be seamless — it was designed by competing interests, and competing interests produce borders.

The crossing itself is a checkpoint complex that processes 80,000 people per day in both directions. Most of them are commuters — Kenosha's housing is cheaper than anything south of The Threshold, and Milwaukee's labor market pays better than GLMZ's lower tiers for comparable work. The checkpoint is operated by a joint venture between Axiom and Sentinel North (Milwaukee's dominant security contractor), and the handoff between their systems is where things get interesting. Each operator scans for different things. Each operator flags different behaviors. The gap between their criteria is a space that smugglers, data runners, and people with complicated identities have learned to navigate.

The city itself is split by more than jurisdiction. East Kenosha, along the lake, is an automated port facility — a smaller version of Waukegan's cargo operations, handling Great Lakes shipping that's routed around GLMZ's more expensive dock fees. West Kenosha is residential sprawl: modular housing, strip commercial, and the particular kind of automotive repair shop that fixes vehicles designed for roads that no longer exist because the roads were replaced by the maglev but the vehicles are still cheaper than maglev passes. The center is the old downtown, now a commercial strip catering to the commuter population — fast food, augment maintenance, and lawyers who specialize in cross-jurisdictional identity disputes, which is a legal specialty that didn't exist thirty years ago and now employs 400 people in Kenosha alone.

The border economy is Kenosha's economy. Everything that costs more on one side costs less on the other. Augment firmware that's restricted in GLMZ is available in Milwaukee's zone. Data that's protected under Wisconsin charter is tradeable under Illinois charter. Pharmaceuticals, weapons modifications, neural patches — the price differential created by different regulatory frameworks is a permanent economic engine, and Kenosha is the cylinder where the combustion happens.
