I know it is a LONG way off but the Brewers and Cubs meet on Sept. 27th this year at Miller Park. Last year I organized a group to go. This year I plan on doing the same and would love to meet some of the folks from here that I have not met yet.
Check out the info in this link. I would organize more here, but I want to concentrate all the organizing in one spot, otherwise the chance of screwing up things would be too large.
