Nothing like when a marginally-maintained lawnmower is fired up for its first work of the morning. Why are there no emissions requirements on these things, and why the HELL are leaf blowers even ALLOWED in this town??? Are there lots of leaves? All they do is create dust, pollution and noise and just move the crap to your neighbors yard, who just blows it back unto yours when it is his turn…

I see no lawn mower in this picture. Therefore it is most likely that this cloud is emanating from your car.
I do see Jesus just to the right of the palm tree, however.
This is another sign. Repent while you still can.
