The Rogue Valley and surrounding areas in Oregon (= Jackson and Josephine counties) provide a higher quality of life for their residents than any other place in the U.S. provides for its residents if you weight the argument like this:
-- 30% Climate.
-- 30% Natural environment. Mountains, streams, forests.
-- 30% Recreational opportunities. Hiking, skiing, mountain biking, fishing, hunting.
-- 10% Air quality.
