The Railroad Tunnel Trail, near Boulder City, NV, follows the path of a rail line built in 1931 to haul materials to construct Hoover Dam.
It's usually possible to walk all the way to the dam, but the trail was closed at last of the 5 tunnels for construction.
You get beautiful view of Lake Mead on one side of the trail.
It took 5 months, working round the clock, to drill the tunnels, through hard volcanic rock.
Portions of some of the tunnels have since been reinforced with wood.
At one place on the trail are some broken concrete plugs that were used as placeholders in the powerhouse floor of the dam until the turbines were installed.
We were very near Vegas and one night went to karaoke at a honky-tonk at the Treasure Island casino. Where else would you see karaoke singers in outfits like this?
I even got to meet Willie Nelson! (Believe that and I'll tell you another one...)
