It's pollen season here in the south, and here in the south, pollen is not just an abstract thing that floats around and makes allergy sufferers complain. Oh no, it's a fine yellow dust that coats, I say coats, everything. These pictures really don't show you the full scope of the coverage.
On the doorstep one you can kind of see footprints, and get an idea of what color the doorstep is supposed to be.
I'll have to upload another picture when it rains, when the streams and rivulets run bright yellow with plant spooge.
