The Railroad Tunnels at Lake Mead are a wonderful day hike or bike ride location close to town. The tunnels are left over from the construction of the Hoover Dam. Trains carrying huge pipe segments and other supplies made their way down to the dam site from Boulder City and elsewhere. This is another neat place near my town here in Nevada that not a lot of people go too. 11 frames HDR and a veritable butt load of post.
