as Dan mentioned yesterday while commenting on the previous image, the fabled canyon is a very busy place...there are hundreds of visitors, but the crowda are held back here and there by the guides of a photo tour, such as the four of us joined (the cost was comparable to renting a hotel room!!)...even then, there were 10 or 12 photographers jockeying for position in the very narrow spaces, and the guide rushed the group forward at an alarming rate...we persisted and everyone got an image or two, but the going was tough...evidence of the high speed adventure is clear in this image, as absolutely nothing is in sharp focus...when you have 30 or 40 seconds to frame up, focus, and correct exposure settings, the odds are definitely against you
