Hiking in the sierra with Neil Randhawa, we saw this. The mountains were beautiful on their own, that’s true, but the clear, straight line of the contrails behind the plane added to it. The juxtaposition of the regular and the irregular is, I suppose, what makes such a striking image and it makes me think of the value of contrasting perspectives, a theme of the conversations Neil and I were having as we walked through the snow and ice.
