While out looking for the elusive condor, we were out on one of the hiking trails at the Grand Canyon and came across a park ranger. We asked; was there a place to see condors? She replied "they often show up at the 3:00 p.m. talk right behind the main lodge". Sure enough, they did and Don had no end of fun carrying the case for our 600 f4 lens saying "make way; National Geographic coming through."
