Chicago in 1830 was a military post and fur station where wolves prowled the streets at night and only 12 families lived. Just 30 years later, it had grown to a city of 100,000 and hosted the Republican National Convention.

I learned this the other day while listening to a book on tape, ``Team of Rivals'' by Doris Kearns Goodwin, which is really all about Abraham Lincoln, but became for me just one more affirmation that change is not endemic to now. Cities grow. Businesses fail. The sand we build our lives on is always shifting. That's life. Nothing stays the same and the world in which we grow up, the world we know, is never the world in which we grow old.
