Turns out that the crud isn’t from passing airplanes. It’s from feasting bees. I forwarded the Ziploc bag full of tiny brown flakes you mailed me to Lawrence Wayne at Forensic Analytical Laboratories. He examined them under an electron microscope and determined the goop to be bee poop. He also pinned down exactly what the insects are eating: dandelion, eucalyptus, and pine pollen. Sounds like a boost they’d sell at Jamba Juice.
