I can't look at this photo without thinking of my Dad and how he hated Johnson grass... he was always zapping it if he saw any emerging on the farm. It freely reseeds and soon takes over. He always said it was too tough a grass to make good hay for the cows, just fit to line a stall in the barn. But it works for a silhouette photo of a sunset.
This was taken back in June.... the sky was so pink...
