Surfer swims for his life FEB 07 2013
Remember the guy who rode the alleged 100-foot wave? Here's a video of some other tow-in surfers from that same location (Nazare, Portugal) on the same day. The waves aren't quite as big as 100 feet, but the sequence starting at 1:52, where the guy falls off his board and swims like hell to get out of the way before the whole ocean crashes down on top of him (watch the top of the wave), gives you a real sense of how insane this sport is.
Great use of high definition and slow motion. (via @alexismadrigal)
