I've done it twice. The first one was when I was living in Cincinnati. It was also freezing cold... I ended up walking up to 4-5 miles and somehow ended up walking up at a hospital. Was paranoid and confused. Not sure what made me get to the hospital but I did. They couldn't even take my temperature because I was so cold. Of course I ended up at a psych hospital after they checked up on me and made sure I wasn't physically sick.
