Why go to the Grand Canyon

I just read this in a blog post about some people who ran a double crossing of the Grand Canyon in one day (South Rim to North Rim and back to the South Rim again):

View along Eminence Break hike.

I don’t want to go around telling anybody how to live their lives; heck, I usually don’t know what’s coming next in my own.

But.
If you haven’t.
Go to the Grand Canyon.

Writing the reasons to see it are like trying to capture the canyon in a photo.
Go and you’ll understand.

That sums it better than I ever could.
