“Well, it’s been a quiet week in Lake Wobegon, Minnesota, my hometown, out there on the edge of the prairie…” The News from Lake Wobegon comes to Fish Creek as Garrison Keillor, writer, humorist and radio personality — most well known for hosting A Prairie Home Companion — brings his tour to Door Community Auditorium July 30. In advance of the show, Arts & Entertainment editor Sara Rae Lancaster caught up with Keillor by phone to talk about the tour, how he approaches writing for the stage versus the page, and why getting older is the best exercise for learning to live in the moment.
