Really nice video though, A+ would watch again. Is there a way to see the full documentary that NZ mentions? And dannnng that is cold water. I swam in Lake MI when it was around 55f one year and that was rather cold, I remember only staying in for about 15-20 min at a time (it was just my brother and I at the beach too...perhaps stupid now that I look back on it.)
