Update: Due to the humongous snowfall dumping on the Chicago area, I have already been notified that one event is bing moved to next Friday, while others may be closed or cancelled.I don't have resources to run a Emergency bar Closing service (although that would be awesome), so please call ahead to any venue you might be planning to visit this weekend.
This weekend starts beer stuff related to Valentine's Day and Mardi Gras in Chicago. Additionally, next Saturday is the Cider Summit at Navy Pier. Tickets are already sold out, but there will be cider-type events going on through the week. I'll try to get next week's busy calendar posted here shortly.
