Illinois and Western U.S.
Illinois (Chicago area): Awful. Lived there as a child, was often miserable.
Northern New Mexico: Moderate symptoms, but a tremendous improvement from Illinois.
Northern Utah: No symptoms whatsoever.
Eastern Washington (Tri-Cities): Bad, too much airborne dust.
Western Washington (Seattle): Light symptoms, dramatic improvement.
Western Oregon (Portland): Awful. Ryegrass season was sheer hell. 80-90% of the world’s ryegrass seed is produced in the Willamette Valley! Brought back long-suppressed bad childhood memories.
Coastal California (Santa Barbara and San Francisco): Very few symptoms.
Best compromise between personal preference in climate and symptoms has been Seattle area; probably anywhere on coast or Puget Sound area would be as good. — DWB, Washington
