Festivals are more prevalent in the summer because of the warm weather, which allows people to walk around without the discomfort of bulky clothing or boots filled with unmelted butter. Make sure the butter in your boots is liquid with today's Groupon: for $16, you get a weekend pass and three premium beers at the Party at St. Mike's (up to a $33 value) held June 10–12 at St. Michael in Old Town.

The annual summer festival churns out live entertainment, children's activities, and adult beverages while raising funds for St. Michael in Old Town Parish. Sip Blue Moon and Leinenkugel’s Summer Shandy while letting tunes played by Hairbanger's Ball, Trippin Billies, Michael McDermott, and other Windy City music makers, careen off your eardrums and into the music part of your brain. Children can entertain themselves during the Sunday afternoon family jamboree, which features carnival games, crafts, and face painting. The shindig's proximity to the Old Town Art Fair lends itself to interfestival revelry and shouting matches between opposing festival-goers.
