Immediately south of Red Deer looking straight west at 9:51pm MST, Aug.28th, 2013.
I was about to give up on this little storm. A fair bit of lightning, but I kept missing the strikes, or I might only capture a bit of one. It had appeared to be over with no further strikes, but I kept thinking maybe one more, and kept at it. This was literally the last strike from the storm. So thankful to get to witness this awesome power and capturing an image like this is a huge bonus!
