In a case of exquisite timing, the entire subway system is borked following a power outage on the day I'm supposed to head to Brooklyn for this month's Secret Science Club lecture. I decided to leave home an hour early, and am now at the mercy of the MTA. They have a good track (HA!) record, so I have no doubt about getting to Gowanus, but it may be a slow ride under Manhattan.
It sure beats braving the NYC traffic, though.
