a wind in the tunnel

A subtle experience: when taking the T from Harvard to MIT, it is best to wait at the end of the platform — getting on the train there lets you off in front of the turnstiles. When standing near the tunnel that comes from Porter Square, you can sometimes feel a gentle breeze generated by the train hurtling down the track before hearing the low rumble of the wheels on their track. We sometimes forget the nerves on our faces are so sensitive.
