Grand Teton was the first national park I ever visited, and it remains my favorite. The first place I stopped on that first visit was Mormon Row and the Moulton Barns. I felt like I was stepping into a wilder, bygone frontier version of Wyoming – bison grazed in the fields all around, eagles and owls hunted overhead, and the mountains stood an enduring siren song to a primeval world. I had the very same feeling – and the breath sucked from my lungs – on our Go Ahead tour of Grand Teton. It was amazing to share one of my favorite places in the world with 34 new friends, and to witness their reaction to what for me is as close a sacred place as there is.
