I always try to have a camera with me when I am out-and-about. Frequently I have a dSLR, almost always an iPhone 6s+, and more recently an 18mp Lumix point and shoot.
I had spent a rare day in the office in the metro so I had an extended evening drive back to our rural home. There were some scattered clouds which made a colorful sunset. I was on a conference call while driving so I put the call on mute, found a spot on a nearby gravel road to pull over and swing the Jeep into a position to take a few picture through the open window with the point-and-shoot camera.
The best best part was that it did not even disrupt the call or slow down the drive home. :-)
