I have also noticed an increase in dust in our home. Since I am the main cleaning person here I notice things like this. It’s been driving me crazy actually as I try and figure out where the source of the dust is. I’m in Arkansas so quite a bit away from you. Everyday the skies are completely covered in trails or thick fog despite us not being in a flight path at all. Twice this week we have had very low flying planes overhead and what appears to be a grayish coating on cars. We basically have only dirt roads out here but the dirt isn’t gray… makes me wonder.
