I take the park and ride Boston Express out of Londonderry when I go in (office in Cambridge). When mapping out my different commuting options plus cost, I decided the bus was the best, given the time I spent didn’t change that much but the cost was drastically more expensive to drive. But it’s still a loooooong day (I’m away from home 5:30-7:30), so I only do it when necessary, which ends up about 1x/quarter. I don’t know how some people make the commute regularly, but kudos to them.
