The September issue of National Geographic Adventure is out with a spread from the Texas Water Safari. It's a shot of the winning 6-man team right before they exited the Guadalupe River for the final 3 mile stretch across the bay.
The image was shot at 11:30pm under a near full moon. I drove for a few hours (thanks Joey) to catch up with the leading team at the finish line. Arriving early, I found that their was an old wooden bridge that could make for a good vantage point during their last stretch of river. I arrived, setup, swatted off mosquitos, and had about 5 seconds to catch them with the flash before they were out of range.
