I think BR is 10th worst on a GOOD day! Funny thing. When there, we were constantly giving my son treatments with a nebulizer and whatever they gave us to put in the dang thing. His pediatrician was close to giving him an asthma diagnosis.
We moved to Shreveport, and I’m not even sure where his nebulizer IS right now.
Yeah, I hate the air quality here in Baton Rouge, especially in the spring. Had a wheezing attack a couple of weeks ago, the first in my life EVER.
It’s all the crap spewed into the air by the Exxon Mobil plant and whatever other plants are around here.
