Some Feedback

"Well, I reckon you've been a pretty good horse," said the farmer. "You work hard and I ain't had to call the vet on you much. I only wish you pulled the plow a little faster."
"NO!" said the horse, "I said 'feedbag' not 'feedback'."

Golden Gate Bridge opened to pedestrians

In 1937, the Golden Gate Bridge, San Francisco was first opened to the public as a Pedestrian Day. By 6 am, 18,000 people were waiting for the toll gates to open. Many crossed in unique ways, hoping to be prize-winners as the first to establish a record, whether by walking backwards or on stilts, tap-dancing, roller-skating or playing instruments. It was a sprinter, Donald Bryan, from San Francisco Junior College, who became the first person to cross the entire span. At 10 am, Chief engineer Joseph Strauss gave no speech, but instead read a poem he had written for the event. By the end of the day, about 200,000 people had joined the celebration. The bridge was ceremonially opened to traffic the next day, 28 Feb 1937.«
