Every spring clouds of green pollen descend on Austin, bringing misery to allergy-suffering public radio reporters like me and frustrating drivers like DeAunderia Bowens.
"You know I just got my car washed and literally got up the next morning and my car was covered with this green stuff!" she said on her way to work. "If I had a green car, it would be all right, but clearly it's not working on a grey vehicle.”
This time of year the stuff is oak pollen, but why does it get everywhere? The answer might make you look at trees a little differently.
It turns out we are surrounded by tree sex.
