Deer ticks live in wooded areas, along trail edges, and in tall grass: the more of that a town has, the more places ticks can quest.

Cook County reports about 2 Lyme cases per 100,000 people a year, the 0th-highest of 0 Midwest counties. That county-level disease pressure, combined with Riverdale's local habitat, sets how high its daily score can climb when the weather and season allow.
