I now have proof that there are sunrises that are complete duds no matter where you are looking. Today there was quite a bit of clouds and even some fog. Still, I headed out to the Walmart parking lot to give myself a chance.
I committed the additional sin of leaving the car on for heat and listening to the radio.

Around sunset time there was some limited purpling, but the cloud cover remained all day, though the fog seemed to lift. I didn't go a chasing the sunset.
