For those who aren't from the Chicago area, taking in a baseball game might be a fun thing to do. Chicago has two teams, the White Sox and the Cubs. I see the Cubs are playing home games on Saturday and Sunday before HostingCon, while the White Sox play home games on Monday, Tuesday and Wednesday evenings during the conference, and also Thursday and Friday.
He's actually the Joe Thornton of soccer really (for those that follow hockey.) Will be interesting to see if Chelsea treats it as a "friendly" or not.
As for baseball, as awesome as it would be to get to a game, not in the cards for this trip. I do need to make a pilgrimage to Wrigley Field sooner rather than later. Of course that usually involves waiting outside the stadium for seats or scalping.
The chicago whitesox stadium is like 3 blocks from my apartment, and I've gone to one game. The games are much more entertaining in real life as opposed to watching them on tv, and I would encourage any non-baseball fans take in a game. I didn't care for baseball at all prior to going to a game, but going to a game changed my opinion of it.
