What U.S. city has the highest pollen ranking?

I have allergies in sacramento which probably stem from flowers, trees and grass. Im looking to move to a city with less of those. Any ideas?

Many people move to dry places like Arizona or New Mexico for allergy relief. However, in recent years, they use landscape sprinklers so much that the effect is reduced, so you would need a more desert-y place and not one that is very green. (It's more environmentally proper, too!)
