A different world . . . well, maybe not. The funny thing was, while all my preconceptions about sea trout fishing involved large, wide-open rivers, the Irigoyen, from bank to bank, reminded me a lot of the best brown trout water I fished in Michigan (like the Pere Marquette) in my younger days. Here I was, half way around the world, and the river seemed oddly familiar, with log jams, and tree stumps, deep pools, and coffee-colored water. We used single-handed rods, and threw streamers and nymphs with short casts into the structure to elicit violent takes. Here guide Nico Trochine points out the best shot to Ann Hamner. Kirk Deeter
