A long time ago, when I was a little girl I went to the circus at Madison Square Garden with my family. My mother's parents also were there, in separate seats. I volunteered and was selected to be a part of a parade of kids and got a shiny hat which I kept for years. And while going around the ring also got a chance to wave at my beloved grandmother and father whom I spotted in the stands because they were waving insanely at me! It's a treasured memory.
But I always wondered why Madison Square Garden was called that when the facility was no where near Madison Avenue. Well, in another fun bit of New York City history, here's the story from the New York Times. And it has to do with the circus and P.T. Barnum. It's a fun read. And there's a great video at the link too as well as a walking tour to down load and listen to while you walk the city blocks.
