Upon arrival, guide Alexander Trochine, showed us a photo of this brown trout he had landed a few nights earlier. Along with his twin brother, Nico, Alex is tasked with figuring out the complexities of the Irigoyen, where they are starting a very limited (four-angler) guide operation. The brothers grew up in Bariloche, and formerly worked as guides on the fabled Rio Grande, known as the sea trout capital of the world, 150 kilometers to the north. "Do you think we might catch fish like this?" we asked Alex. "Claro que si . . . of course," he answered.
