Hi, A little anecdote taken from a Readers Digest book thingy, that I read about 50 years ... "First Lady of the Seeing Eye". A blind man in New York had called a press meeting to publicise guide dogs. The journalists were not impressed, but one promised to write an article if the dog could safely escort him across a certain street. The challenge was accepted, and off he went. It took for ever to cross the street, and it sounded like he upset a lot of drivers on the way. Eventually he arrived at the other side ... to find the journalists had taken a taxi. It was too dangerous to walk across. 602
