You'd hope that Oak Park, Evanston, Wilmette, and then Berwyn and Schaumburg could get this done, and then your next step would be either Chicago (tough because of aldermanic structure) or statewide, the way California did. Either way: you start in one municipality and work from there.
It helps that zoning matters more in Oak Park (and Evanston) than almost anywhere else in Chicagoland.
