This was taken summer of 2010. We were driving to my in-laws house in southern Minnesota. When we pulled in the driveway, I looked south and saw this HUGE thunderhead rolling across the farm fields. We got the kids inside and I took off outside to fight with the mosquitoes to get a few shots of this storm. This one was a 6 second exposure. I adjusted some brightness and contrast, but that was it. No lightning bolts are photoshopped in.
