We just finished the Vice Guide to Chicago. It has some crucial shit in there for Intonation including a map of the park and a list of who plays what stage when. There's also a guide to bars, a guide to eats, Chicago music, Chicago DOs & DON'Ts and Chloe Sevigny getting shitfaced for $10,000. If you're visiting Chicago for Intonation or ever for any reason you need to download this and have it all folded up in your man purse the whole time you're there.
