Despite the snowiest Halloween in Chicago history, trick-or-treaters young and old took to the sidewalks of 111th Street on Oct. 31 to enjoy the annual Mt. Greenwood Chamber of Commerce Trick or Treat Safety Walk. Decked out in costumes, local residents collected treats from participating businesses, and smiles were aplenty in weather more suitable for Christmas than it was for Halloween. According to reports, 3.4 inches of snow fell in Chicago, and it was the second-snowiest October day in the city since Oct. 19, 1989. The high temperature for this year’s holiday was a scary 35 degrees, the third coldest in Chicago since 1871, and the low of 24 degrees was just 1 degree warmer than the record temperature.
