The calendar may say Saturday belongs to September, but that won’t stop the 28th annual Northside Oktoberfest from bringing beer, brats and Bavaria-inspired family fun to Iowa City starting at 11 a.m. As is traditional, a stair truck from Eastern Iowa Airport will be there (Fly CID is a festival sponsor) for photo ops from above, and this year there will be more than 45 breweries and wineries providing samples to ticketholders.
