After Jackson, which got an allergy score of 100 (that's terrible, FWIW), Louisville, KY, is the second-worst for itchy eyes and snotty nostrils, with a 98.34 score. And next up, Oklahoma City, OK, which had the third-worst pollen rate in the country, and a 95.64 score.
But it wasn't just the South and Plains States that had it worst -- really, the top 10 spanned the whole nation. So if one thing unites this Union, it's allergies.
And as for the best place to be, that’d be San Diego, CA, with a score of just 42.60. Everyone in San Diego nods in unison, bathed in sunlight and warm temperatures.
