[Star Tribune, September 09, 2009] Minnesota humorist and author Garrison Keillor had a minor stroke Monday. A Facebook page for the host of radio's "A Prairie Home Companion" initially reported his hospitalization, unleashing dozens of get-well wishes in response. In a statement released through his St. Paul-based radio show, Keillor said he first went to United Hospital's emergency room in St. Paul, "where I got excellent care and then was transferred to Mayo simply because they know so much more about me down there."
