One experience that came to mind when I first encountered this "Deep Travel" meme was an unusual canoe tour.    It took place years ago at Wyalusing in southwestern Wisconsin, where the Wisconsin River meets the Mississippi.   My girlfriend and I were camping at the park there, and one morning we took an official tour of the "canoe trail" that wanders through the sloughs and backwaters of the Mississippi River. 

The park ranger leading the tour was a personable young man whom I later assumed was a recent college graduate and former art student (for reasons to become apparent below).    As expected, he pointed out various features concerning the wildlife and natural history of the lowland river territory we were exploring.   Then he pointed to something in the water near the shoreline of one of the many low islands we were passing by.  

"Look !  A Monet !  See how the ripples reflect those subtle pastels !"

Before long he spotted another.   "Cezanne !  The brushstokes are unmistakeable !"  

And around the next bend he pointed out a fine example of pre-Raphaelite painting.

And so it went.  

Even though I had only a passing famliarity with the artists and styles involved, I could still see the differences in the reflections and appreciate the enthusiasm with which they were being indicated.   This certainly added an unexpected new dimension to the whole experience of paddling around the sleepy backwaters of the muddy Mississippi !

Suddenly seeing familiar things in an unfamiliar light.    I think that is one indicator of a "deep travel" moment.

Since that day I have paid more attention to reflections in the water.    Especially in autumn when the leaves in Wisconsin change color.    Even a relatively dull display of fall foliage can become as psychotic as a painting by Van Gogh when distorted by flowing water.
