Spring allergy score: 94.41 Move to Chattanooga and you can expect your breathing to sound like a choo-choo this time of year if you have springtime allergies. That's because the 530,000-person metro area has worse-than-average springtime pollen counts, with lots of allergens from red cedar, hackberry, elm, willow and poplar trees. The south Tennessee city also has higher-than-average allergy-medication consumption this time of year. "Chattanooga has the exact same story we see in many cities with bad springtime allergies -- very high pollen counts and very high medication usage," Tringale says. On the upside, the Scenic City does enjoy an above-average ratio of allergists to patients.
