None of the injuries appeared to be serious, Tampa Fire Rescue spokesman Jason Penny said. The strike kicked up rocks and gravel and knocked a few people down when it hit around 4 p.m.
"The boom came at the same time as the light did. It was like the speed of sound type thing. And it was loud. It scared the heck out of everybody," Packers fan Rudy Hynek said. "It was amazing nobody was killed."
Bruce Kudick, of Sarasota, said the lightning appeared to hit the top of a car and "shattered the top" of it.
"I never saw a streak. I just saw this huge flash. It was like the sound and the light was at the same time, so it was like a bomb went off," the Packers fan said.
