We had quite a nice lightning show last night! It was one of those rare times when lightning was flashing all around the sky but there wasn't any rain falling (although it did start raining after most of the lightning had passed us by). It also was not windy at all. Last but not least, most of the lightning was up in the sky and not making any apparent ground connection. I made this photograph looking at the summit of Mt. Rose in Grand Portage National Monument. It was a 12 second exposure at f/5.6 and ISO 400.
