This weekend brought us some of the coldest weather of this winter. Be on the lookout for anyone who is not dressed appropriately or who seems to be suffering. Err on the side of safety. Notify authorities. You can call the shelter hotline at 1-800-535-7252. They can send a van to check on the person. If it looks more serious call 911. The police and EMS are happy to check up on people who are out in the cold.
