I just looked it up on google maps and I live 3.5 miles from work if I were to walk it (which, seriously, I never will), but 6 miles driving (darn city roads). I share a car with my boyfriend, but neither of us drive to work regularly because we'd have to pay for parking. Although, we could get monthly parking passes that aren't TOO expensive, but the problem is parking at home after work, as we only have street parking and it can get really tough from 6pm on to find a spot.
I take the bus to the train. On a good day it's 30 minutes door to door, but I always give myself an hour just in case I have to wait more than I'm expecting. I have an iPhone app that tells you when the bus is coming, which has made waiting for the bus infinitely better. And the trains come often enough that it's not a big deal.
