Here is a video showing over half dozen fires starting at the same time! Large distances apart!

As a side note, the smokey haze here in S.E. Michigan is incredible.....
Don’t believe everything you see on Twitter or YouTube.
I have seen the same video. What they edited was the storm front that went through the area prior to the clear skies.
These eastern fires started in places where there are no roads. Logging roads are gated off to keep people out in the summer so that they do not accidentally start a fire.
