True, pollens can travel for miles, but some places are just worse for allergy sufferers than others. The Asthma and Allergy foundation has released this year's Fall Allergy Capital rankings, or in other words, "the 100 most challenging places to live with allergies" based on the following criteria:

• Pollen scores (airborne grass/tree/weed pollen and mold spores)*


• Number of allergy medications used per patient


• Number of allergy specialists per patient

So where's the worst city for those with seasonal allergies this fall? Greenville, South Carolina.

You can download the full list of the rankings, including the survey methodology, here (pdf file).
