I've always wanted my own paddleboard just to chill out on, but after watching this frightening video, I'm rethinking that. Mike Durand of Manhattan Beach, California had a scary encounter. He was out on his paddleboard when a great white shark got a little too close for his comfort. In fact the shark swims directly underneath his paddleboard. The scary moment was captured by his helmet camera, watch it and see if it doesn't raise the hair on the back of your neck.
