I'm going to the Jimmy Buffett concert tomorrow, and we're going to tailgate for a few hours beforehand. I'm in charge of bringing beer for myself and a few others. I'm looking for a good summer ale. All of my friends are beer lovers, so I don't feel obligated to get any BMC. Given that I live in Chicago, Goose Island 312 and Summertime are a popular choices, as is Leinenkugel's Summer Shandy, but I'm looking to try something new. Any thoughts?
