As we're slowly dragging through the ass end of winter there is no better tonic for all the gray skies and slush than a trip to the steamy greenery at the Garfield Park Conservatory. The Conservatory is currenly hosting an exhibition of African dinosaurs, most of which are arranged in ways you'll never see at the Field Museum. And if that's not enough reason, admission is free if your conscience will let you walk in without kicking in for the $3 donation. You're telling me you don't want free dinosaurs?
