I stayed out capturing these photos until the lightning was within about a mile or two of me. The sound was deafening! I literally had to put ear plugs in because it was painful. My wife thought I was crazy too. ;-)
The full sized versions of these photos can be found on my Flickr account, or a smaller album is also on Facebook depending on your preference.
And here is a 2 minute video of the actual storm that these photos came from.
