Woodard asked, “So, where does this rank on your bucket list?”
He replied, “It was the No. 1 thing I wanted to do, to be honest, to be out in the water and see and ride one of those.”
The kids on the boat went for a ride too. They weren't in danger. Whale sharks have no teeth and despite their giant size they prefer eating small fish, not humans.
Riding a whale shark is not illegal, but marine biologists say they could get germs from human contact.
