I'm always surprised that more people don't bike to work, if they can do it in a reasonable amount of time and safety.
Basically, the idea is that for every mile you live closer to work, you can afford another $15,900 worth of house.
It's also interesting when you throw in cycling to work; I used to argue with a friend about going to the gym (which I'm not fond of). I told him I could bike to work (20 minutes) and bike home (20 minutes) for a total of a 40 minute workout during my commute and save myself the extra hour (maybe more) it would cost going to the gym everyday.
