The Google Trekker for Google Maps

When reading the Google Blogspot this morning, I recognized "The Trekker."  OMG!  Just last week, when I was driving home I saw what appeared to be a large helmet on a post on top of  a car.  It was so unusual that I drove closer - wondering if it could be a bicycle on top of the car with a large red helmet on top.  But then - the vehicle turned left and I could clearly see that it was not a bicycle, but a post.  When reading the Google Blogspot this morning about taking pictures of the Grand Canyon for Google maps - there is was!  I had followed a car with a Google Trekker mounted on top.
