LIFE IS GOOD: Thursday I dropped my wife and son off at Midway airport. Friday I sat in the front row as Al Gonzales sacrificed body and soul to win the Illinois super-lightweight championship and remain the Windy City's best boxing prospect. Today I dragged an old TV and a six-pack of Schlitz cans on my back deck to watch the Yanks and Cubs at Wrigley. Now I'm sitting here singing along to the Beach Boys at high volume. And tomorrow I'll pick my wife and son up again, the capper to one of the most perfect weekends of all time.
