@KaysHealingPath I avoid chicago at all costs. It's such a dirty city. I'll never forget the black smog haze we saw hanging over the city as we got closer the last time we went through the city.
@AcidBurn I think that @SW-User May be right. I think that moving larger manufacturing industries out of the city has significantly improved our air quality. Obviously it’s not perfect but it is more prevalent in larger cities.
