In the early hours of January 26, the temperature in Madison reached minus 20 degrees due to the polar vortex. By the time Tom Wilson was walking his dog that Saturday morning in his neighborhood on Proudfit Street and West Main, the temperature had only risen to about minus 13. As he plodded through those frigid conditions Wilson noticed a man and a woman on a corner who looked to be in some distress and walked over to see if something was wrong. “Can you help me?” the woman asked. She explained she had found the man out in the cold, incoherent, and she didn’t know what to do.
