This video is terrifying. Big Wave surfer Chuck Patterson was stand up paddle surfing in San Clemente, CA when two sharks circled him for 15 minutes. So of course, he went back looking for them the next day.

"The day before I shot this video, I was SUP [stand up paddle] surfing with a couple friends and 2 sharks circled us for about 15 minutes. The next day, I decided to go back out at around the same time and take my camera mounted on a 10 ft pole and do some exploring. Sure enough within 5 minutes, a 9 ft shark came out of nowhere and circled twice and slapped his tail on my board before disappearing. Then a minute later, a 7 ft young juvenile Great White swam circles around me for 12 minutes."

I'm not sure what kind of combo of bravery and complete foolishness you have to have to do something like that, but wow. Watching this video and knowing that the only thing between the cameraman and those rows of teeth is a little fiberglass plank makes this pretty intense.
