CANOE & KAYAK recently ran a feature on The Texas Water Safari, self-billed as the "Toughest Canoe Race in the World". The 260+ mile canoe race has been going on since the 1960s and takes place in the summer.
I shot the images during the 2007 race with balmy temperatures above 100 degress. 2008 was one of the lowest water years on record and I heard the race all the more challenging in low water. Only 53 of the 100+ teams finished in the allotted time. The story is available online here.
