While photographing more-distant lightning (see the bolt at left rear?) a bright flash blasted through the sky beneath a base higher than the field of view, around two miles away. This was unambiguous evidence that it was time to toss the tripodded camera into the back and evacuate the area, fast. Unlike a similarly close discharge a couple weeks before in Norman, I wasn’t within any sort of shelter.
