Occasionally you can't or don't feel like riding to work (weather, health, bike failure/loss...). How do you go to work, then, usually? (This is a poll)
Also (not in the poll), what's the degree of your unhappiness when you have to use other means to commute than bike? e.g. I'm very unhappy to take the smelly, dirty, crowded subway that is not only unreliable (schedule-wise) but also sometimes dangerous.
