The locations he was located at are relevant because they show the huge improbability of the strikes. INSIDE the ranger station? Driving his truck? His own front yard getting his mail? Fishing at a pond? Nothing about these locations make being struck more probable, and certainly not to the same man.
Driving in the mountains doesn't increase your odds of being struck by lightning? Having a career as a national park ranger in a mountain park doesn't increase your odds? OK then.
Something is making them happen, against all the odds of them not happening.
Yep. Statistics.
