The oak trees in the evening sun look like they might be arrayed in their autumn leaves, but . . .. . . no, it's their catkins, spewing pollen over all creation, including me and up my nose, "Sniffle, sniffle."
Soon these catkins will drop all over the roof, the deck, the yard, and the patio, making their own kind of mess. Fortunately it's not quite as bad as the leaves in the Fall.
