Yesterday I had a tour on South Kaibab, and there was so much graffiti!  I did not want to stop with my group every few feet, so I went back today and it took me two hours to erase everything down to Cedar Mesa.  Here is the poem I wrote whilst hiking back out.  Xarlo is Lorax spelled backward.

I am the Xarlo

I speak for the rocks

To protect them from those

With heads full of blocks.

The rocks by themselves

Are pretty much matchless

They are not improved

By your infantile scratches.

Your hearts and your names

Your dates and your wit.

Your drawings of dogs

You know what:  just quit.

The facts of your deed

You wish to exert

But just take a picture

 Or buy a tee shirt.
