I have been going through photos from the first trip this past spring, and happened upon this one, from a lovely afternoon in Boulder City, Nevada. The National Park Service has built a gorgeous hiking trail that follows the railroad line that brought supplies and building materials to the construction site of the Hoover (neé Boulder) Dam back in the late 1920s. The trail follows Lake Mead and ends up at the dam 3.7 miles later.
We had a great hike1, and I got this nice shot of Susan in one of the huge railroad tunnels along the trail. (Click to see it bigger.)
