Day 9 So itchy! Pine Pollen

My car is covered in fine yellow dust as it is parked below enormous white pine trees. A 30+ yearly reaction to pine pollen, I finally was curious as to why it is so irritating today. I looked at microscopic images. I don’t have new ideas as to why it’s so annoying, but I do know why it flies all over the place…each pollen grain has two air sacs which presumably help the pollen disperse on the wind. Here is a synthesis of the many images of pine pollen I reviewed today.
