Lollapalooza, the second big music festival of July, is soon upon us. In fact, you can beat tomorrow's lines by heading down to Grant Park this afternoon to redeem your tickets for the wristbands that will allow admission. Nevertheless, what may prove unbeatable is the weather. WGN forecasts a high of 100º on Sunday, with a heat index of 114º. So, if you're going, make sure to take along the permitted 2 water bottles, and, if you decide to stay indoors and forgo the Trail of Dead outside, one place you can look for reports on festival goings-on is USA Today. The paper is touring the country on a "summer music road trip" and kicks off its coverage of the weekend with this interview with the soon-to-be-50 Billy Idol.
