So, this is the coolest thing I've seen in a while. Twice a year the waters of the Atlantic Ocean roll up the Amazon River, in Brazil, generating the longest wave on the planet. This phenomenon, known as the Pororoca, is a surfers dream: the never-ending wave. This statement, however, would make me think twice about surfing the Pororoca: "Surfers have only recently realized the extreme challenge of surfing the “Pororoca”, despite the fact of the large risks involved; ship waste and wreckage, poisonous snakes, to name just a few."
Check out this video of some pretty crazy dudes catching this amazing wave.
