MASS AIR POLLUTION ACROSS EAST COAST

Did anyone in the Northeast see heavy spraying in the sky today? I did. It was the worst spraying I've seen in years. It had been unusually clear for months, but today the entire sky was full of trails. It was crazy.

Anyways, look what I found just now. An air quality alert across Pennsylvania and Ohio for air pollution. Anons, I've never seen an alert like this in all my years living here. WTF is going on? The same article claims that there are air quality alerts in many East Coast cities, too.
