At about 1,431 residents per square mile, South Jacksonville mixes a compact center with lower-density neighborhoods. Main roads carry most traffic, so a vehicle that lingers is noticed. Observation is kept short and tied to known schedules, and much of the background work happens through county records rather than in the field.
Interstate access and travel
Interstate 72 and U.S. Route 36 run through or near South Jacksonville. Subjects in a mobile surveillance often leave town on these routes, so plans account for highway speeds, exits and where the work could cross into another jurisdiction.
