This was a group trail run organized by Matt Adams (of Fleet Feet). It was raining so hard at the beginning we could barely see. Only 4 of us started out; a few people stayed in their cars and skipped the run. About 0.3mi in there were several loud, close lightning strikes, so Matt cancelled the run. I wanted to keep going, but I was the only one. So I listened to the wisdom of the group and headed back.
