In case you hadn't noticed, it's coooold outside. While we're zipping up our North Face and lacing up our Timberlands to keep warm, don't forget that others are not so fortunate. The city's department of family services is trying to make sure they find warmth and shelter for Chicago's homeless. The city is encouraging everyone to dial 311 if they see someone in need of a place to stay, so they can direct them to one of the city's six warming centers during the day and to a bed at a shelter at night. City outreach workers will be making rounds to find people in need. Also be sure to check in on your elderly neighbors, especially those who live alone.
