It's not just a few days though. I can only speak anecdotally for the pacific north west but... We used to be known for clean air, rating were typically below 20 AQI for almost all of the year. Now, come fall we have weeks/months hovering around 50 AQI. How much smoke does it take to move places like Seattle and Portland from clean air paradises to "LA of the 00's" where just living there gives you the lungs of a light smoker?
