Meet the boys: Trent McCrerey and Knox Hammack. Trent and Knox are pro kayakers that won TGR's community entry for the Tough Fun Film Series, and spent the better part of May and June on a road trip of epic proportions, chasing water levels throughout the American West. Follow their adventure in TGR's final short film from the Tough Fun trilogy, and watch them run some of the gnarliest whitewater in this part of the world.
