It's the Chicago Reader's 40th birthday, and Michael Miner joins us because he's been there for it all. Hans Holsen becomes METRA PR man Harvey Pilker, here to explain fare hikes. Whit Nelson explains science, specifically, neutrinos. Thea Lux performs as Nadine Valentine. And Dastardly comes in with music. As usual, if you can hear us, this magazine is LIVE.
