But last night we were treated to an awesome lightning storm which rolled in suddenly just before sunset and lasted a couple of hours. Fortunately our motel provided a great vantage point for photographing this storm, which approached Estes Park from the east. It didn't seem to move much, so I had many good chances to capture the lightning.
This shot below was taken later in the storm, and since it had gotten dark I was able to stop down the shutter and make a 30-second exposure. I took many such exposures and got a few good shots.
