After capturing images from Preston Beach, I rechecked the radar on my iPhone and saw an approaching rain storm was nearly upon us.  I quickly moved up to the top of the rock wall and positioned myself behind the old anchor for the last few shots.

As the light had faded, I was able to leave the shutter open for much longer exposures and greatly increase my chance of capturing bolts of lightning.  During this exposure, I managed to capture a cluster of bolts situated in the same location and placed perfectly in relation to the old anchor.
