Sunset on the Road

We made a round trip to Houston yesterday and as we headed back into Austin on Hwy 71 I snapped this out of the moving car. Wonder what exotic dusts and pollutions were about to cause such a beautiful display?

    Typically yellows are Nitrogen Oxides (NO, NO2) and reds are Sulfates (SO2).
