Working in a smaller community
At about 788 residents per square mile, LaSalle Township 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

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. The same routes matter for locates: people who move frequently tend to follow them.
