A literary map of London, with its writers and characters charted by neighborhood. Which, this us just about the coolest. The Twin Cities of Minneapolis and St Paul have nowhere near the literary relevance of London (not even close), but I would kill for a literary map of my hometown(s). Here's a start:
--Dr and Mrs Kennicot from Sinclair Lewis's Main Street honeymoon near Lake Calhoun; she's from St Paul
--Much of the action of War for the Oaks takes place in and around First Ave
--Zombie novel Fiend bops around St Paul and the St Paul suburbs, ending in the St Paul County Courthouse
--Meridel LeSeuer's The Girl takes place in the dodgy part of St Paul circa 1920s; not sure where exactly
--Franzen's Freedom takes place in Ramsey Hill in St Paul
-- Diablo Cody worked as a stripper in Sex World, Sheikh's, and other Minneapolis strip clubs, as detailed in Candy Girl
--Though much of Tim O'Brien's In the Lake of the Woods takes place in the Lake of the Woods (doi), it starts in St Paul when the protagonist's bid for governor fails
--Similarly, the (I think only pseudonymous narrator) of Pirsig's Zen and the Art of Motorcycle Maintenance starts in the Wedge neighborhood. Specific streets are named, something like 25th and Colfax
--For sure there's stuff by William Kent Kreuger, Garrison Keillor, Robert Bly, and Louise Erdrich I can't think of right now.
