I am in Chicago for a trade show at the end of August, and a bunch of my bay area colleages are getting together for the Friday, August 31 Giants versus Cubs game. Tickets are $32 each, and are in Aisles 208 and 209, rows 12 through 15. These are what they call the "Terrace Box" section and they are along the left field foul line overlooking the outfield. See http://chicago.cubs.mlb.com/chc/ticketing/seating.jsp and click on the pink seats at the end of the row of red seats.
If any McCovens want to Join us, let me know ASAP. Email address should be visible in my profile, or I guess respond here.
Technically this is the "worldcon" group ticket section (World Science Fiction Convention) but I suspect it will be filled mostly with Bay area folks.
