Lightning Strike
This pick-up truck was struck by lightning on S. Hwy 79. The owner said the truck flashed and completely shut down. The lightning bolt actually struck the top of the truck, causing a fire in the interior of the cab. A vehicle following the truck said the lightning also struck the ground and put a hole in the road. The asphalt blew up and hit the lower side of the truck causing body damage. Pictures and description courtesy of the Rapid Valley Volunteer Fire Department.
