Which is more Minnesotan: Fargo or Garrison Keillor? I can say without hesitation that Fargo captures Minnesota with a deadly certainty that leaves a native like myself feeling like a Southerner who has ambled into Midnight in the Garden of Good and Evil. Fargo is telling not because of its dark, wintry perspective, but because the people in the film are constitutionally droll. Keillor, on the other mitten, insists on monopolizing drollness as his personal kingdom. The Minnesotans he writes about are cuddly grotesques who advance his view of the provinces but who seem to have no real lives of their own. Perhaps all that will change with the publication of Wobegon Boy (a title that will no doubt extend his franchise for a few more years), which is a novelization of the geographic motifs Keillor happily spoons up like so much tater tot casserole. Native churlishness aside, Keillor is certainly among the most readable and listenable humorists going. Just don’t mistake the mascots he deploys to his own ends for anyone who actually lives in Minnesota. Keillor reads and signs at noon at Borders, 8311 Leesburg Pike, Vienna. FREE.
