There once was a lovely little gosling named Julia. She went around gathering traits. When she grew up she fell in love with Xponis, the powerful goose. He would lead a journey south. No two geese are alike. So I pulled out my looking glass and took a look. It's true. The geese did a thing called drafting. This does not mean they stop for a draught on the way south. It means flying slightly behind and to the flank to take advantage of the draft from the goose in front. It makes for easier flight. Bang! It's over. To prepare the goose, Margaret, the chef, takes over.
