21 miles, huh?
Tell work, as I'm leaving, that I won't be in tomorrow, take a week off, claim I got lost walking home <img src="/images/graemlins/smile.gif" alt="" />

Ok, now the serious answer; depending on the time, I may actually attempt the walk. In a blizzard, nope. Find a YMCA, or a bus/train station, and hole up till the AM. Without a wallet, in the cold, you just gotta suffer through the night. Besides, it'll make for a great story when you go back to work.
