Been wanting to blog on this for a long time now. Ever notice on a perfect sunny day in Seattle, just like today, unmarked planes soaring across the sky leaving behind a thick trail of condensation? Is this normal or is something going on up there that we should know about? All we can say is that sometimes those condensation trails look pretty thick and can take a long time to dissipate. And if there just happens to be any chemicals in the trails, what goes up obviously must come down. Anyone got answers?
