Grand Canyon, AZ

Today, day 7, saw us take the Grand Canyon Railway to the south rim of the Grand Canyon.
It is one of the seven natural wonders of the world.
Photos do not do it justice. Its statistics are amazing, eg it would take four Empire State Buildings stacked on top of each other from the bottom of the Canyon to the top and there will be still space left to fill the void to make it to the top of the Canyon.
