Epic lightning storm above Southern Idaho in July 2013. We get lightning storms here, but never anything very intense. When I looked out my back door because I heard thunder all I saw was lightning flash after lightning flash. I grabbed my gear and went outside. This was a totally dry storm that started around 20 new fires in our area. The lightning was incredible to watch though!
