When I was little, in Colorado, my brother and I would get up early on cold mornings and crawl into our parents' big bed. They had a window above the bed and sliding glass doors (leading onto a deck); our house was on the top of a hill and you could see all the way to the mountains with no other houses or trees in between, so we could always see geese flying south for the winter.

The "wild geese" song I always think of is the one (I assume this is the emigration one mentioned earlier) about "when the ship has raised its anchor/come what may I will always care/when you hear the wild geese calling/think of me and I'll be right there" that goes to the tune of "Planxty John Irwin".
