I had a situation a month or two ago where I had a choice: be able to drive my convertible with a friend without my camera (it doesn't fit anywhere except the passenger seat) or ride around in his crappy car. I chose to take him and my car.
That night we met up with some friends at a local lake. An hour later a thunderstorm was moving to the east, for two hours the lightning went cloud to cloud, cloud to ground everywhere.
And I didn't have my camera. I could have cried.
