Lightning strikes have killed at least 20 people in the U.S. so far this year, according to the National Weather Service. That's higher than the average for recent years, the service says.
Most people who are injured or killed by lightning, it turns out, are not struck directly — instead, the bolt lands nearby.
That's what happened to Steve Marshburn in 1969. He was working inside a bank and says lightning somehow made its way through an ungrounded speaker at the drive-through window to the stool where he was sitting.
