...is it worth a flight to Chicago the first weekend in August? Some of the other bands / acts playing in Grant Park that weekend give me a down-right allergic negative reaction. I don't know. Part of me WANTS to go, but a more rational part of me says "bad idea" - like the classic skit, "bad idea jeans".
