Book excerpt: It's easy to get caught up in the hidden history of Ravenswood and Lake View, like the Harm's Park picnic that lasted fifty-four years or the political gimmickry of the "Cowboy Mayor" of Chicago. Who can resist a double take over folk like the "Father of Ravenswood," who kept Chicago from falling to the Confederacy, or the "North Side's Benedict Arnold," who was sent to the electric chair during World War II? If you want to visit the days when the Cubs were the Spuds or debate whether Ravenswood is an actual neighborhood or just a state of mind, do it with longtime North Side journalist Patrick Butler in this curio shop of forgotten people and places.
