It could be VERY cold in Chicago in late October. That might favor the White Sox slightly at home. Houston is pitching very well right now and pitching is all important in baseball so I'd give the edge to the Astros. Houston probably has more veteran leadership with guys like Roger Clemens and Andy Petit on their team.
Thanks for that. I used to live at Great Lakes Naval Training Center on the lake near Chicago. I have never been as cold as I was there! Went to highschool in the early 60's and it was 15 below most winter days when we picked up the bus.
