Not a ton of brewers, but out-door beer fest season is closing fast. This park along the Fox River in Oswego is nicely, picturesque. If the weather is decent this fest could have a great vibe, on this first weekend of Fall. And price is cool at $15.
I'm going to try and make this... It'll probably be like Wheaton Ale Fest with volunteers and not brewers pouring but like you said... for $15 and outdoor festival season ending, it could be worse.
