Purple Sunset

I don't remember exactly when I took this picture, but I know it was many years ago. I suspect it was at Fort Desoto, but I'm not sure about that either. I seem to remember there was a storm blowing through, and it turned the sunset into all sort of odd colors, all in a span of about 10-15 minutes. There was a progression through yellow, orange, red, purple and eventually black. I need to see if I can dig up the whole sequence of pictures from the archives. I remember it was drizzling slightly on me, but I didn't care, because I knew I was getting some great pictures.
