My boots were soaked from walking around in the snow all day. The moisture had been soaking so long that it had seeped into my socks. My feet were wet but I figured getting into the car with the heat cranked up, my socks would dry out and then my feet would be perfectly fine. Sometime though I fell asleep and my car ran out of gas. I figured it wasn't an issue. I was really tired and I wasn't feeling that cold. I would be fine overnight.
