Big Shoulders Realty’s Lee Diamond relaunches his Chicago Neighborhood Bike Tours Saturday at 1 PM in Hyde Park with a five-hour, 17-mile ride starting at Washington Park Fieldhouse (5531 S. King Dr.). Register for the ride, which as usual includes Diamond’s historical and architectural narration, here.

Earlier this year, Diamond announced that he was ending the popular tours for financial reasons: as Big Shoulders increasingly felt the pinch of a struggling real estate market, he couldn’t afford to continue to put what he estimates to have been 80 to 100 hours a month of preparation into the project.
