For now, Los Angeles has a solid lead. Based on the most recent date available to make comparisons, the four-county Los Angeles region posted 34 days in 2000 when air exceeded the national health-based limit for ozone, compared with 26 for Houston. The worst air actually occurs far inland, especially in Crestline, the east San Gabriel Valley and Hemet.
