This picture was taken at 10pm about a week ago. The lightening was amazing. I drove to a road just north of our house to take pictures.
I could have stayed there all night taking pictures, but the storm moved through and and I only got a handful of neat shots. Maybe there'll be a next time.
The lightning was mostly moving sideways. As I recall from what I've heard, that would be heat lightening. It was rather warm that evening, so that doesn't surprise me. We did have a few sprinkles, but not much in the way of rain.
Next time I hope to know my camera better and get some long exposures.
