We’ve been dumping on Mrs. Kroc lately for her left-wing philanthropy–and rightly so. But I’m going to put in a plug for McDonald’s and its philanthropy. I was in Chicago over the weekend for a conference, and slipped away to the Field Museum for a few hours, where I was reminded that McDonald’s recently underwrote the acquisition and mounting of the world’s largest T. rex skeleton. She’s named Sue, after the woman who discovered her in South Dakota (scientists don’t really know if the specimen is male or female). At any rate, it’s a fantastic, dynamic display–and an outstanding example of coporate giving.
