I live 3.6 miles from Logan. MapQuest gives a driving time of 6 minutes, which I cannot imagine. I've done it in 10 minutes when the taxi has arrived at the Arlington/ Beacon traffic light perfectly and there has been no traffic in the tunnel or at its approach. I usually allow 20 minutes at low-traffic times of the day.

One of the best things about Back Bay/ Beacon Hill is that the city overflight patterns from Logan go either over the South End or to the North. I never hear an airplane.
