This is Janine riding the old railroad bed that now makes up the Historic Railroad Tunnel Trail. This is a cool trail, great for biking or walking. It travels through 5 tunnels as is traverses its way above Lake Mead from the Visitor Center Parking lot to the Hoover Dam parking lot – about 7 miles in length if you do the round trip. This railroad was built to assist with the construction of Hoover Dam.
For this photo, I switched to manual mode and exposed for the sunny areas outside the tunnel. Otherwise the camera metering system would have a tough time accounting for the large dark areas.
