Interesting. Plus dragon flies are beautiful. When I first moved to Spokane, we had them on the lawn, but 12 years later you never see one. My neighbor swears that they are cloud seeding with chemicals that kill things.
I have no clue. Do you?
Of course they are, whatever they are putting into the sky via Jets is drying out foliage. Something that is a dessicant for sure. It has never rained more where I live, than in the last 10 years. Yet the trees seem to get burnt, like they survived horrible droughts. Look around if you are in places like Western Washington, Oregon or parts of California. Pine, Redwoods, Hemlock, and Firs easily tolerate temps to 100 degrees in the summer months. They just seem to dry out much more than they did in my youth.
