I had ventured into this reprise of every fraternity party ever because of the NCAA basketball tournament. The University of Michigan was playing, and Fox & Hound, among other things, is a Michigan bar. (One Purdue alumnus, a regular at games here, described it as a "Midwest-theme restaurant," since it is as vast, bland, and filled with Midwesterners as the bars he remembers from college.) Last Thursday, for the Sweet Sixteen, it drew hundreds of March Madness-infected white people -- some in Michigan colors, others in ball caps and popped collars, and still others in rumpled business suits, briefcases tossed at their feet.
