It Was a Mystery Until...
On the road out of Te Kuiti, summer arrived. The tarseal was starting to melt, globules of it glistening in the sun and the bike's tyres hissing on the sticky surface. In the air and on the ground in a couple of places was something that looked like thistleheads blown on the wind. I took several photos and showed them to someone at a DoC office who said it was seed or pollen from poplar trees. As he said it, I remembered seeing several polars lining the road.
