Because
We left after the first inning, as Katie was shivering from the cold, despite being well wrapped in many layers of clothing and a blanket. Mind you, we weren't exactly warm either.
When we left, the Cubs were leading 1-0. I'm watching the top of the seventh now from my recliner at home (and Katie is much happier). The Cubs, on the other hand, are not so happy as they're now trailing 10-2, largely courtesy of a Zambrano meltdown and a Pierzynski grand slam given up by Neal Cotts.
Home is a good place to be.
