Are you not from the south? Every single year the south is covered in pollen the entire month of April you fricking idiot.

Not sure what color river birch pollen is but that was a whole bunch of yellow. I am thinking that birch trapped a bunch of yellow pine pollen. If so, the pollen from a pine (the yellow stuff) is too large to cross the membrane meaning it has very little effect on allergies.
