If you need a ride to or from the airport or the metro this week, call Eric or me. I have at least one friend metroing out to the ceremony the day of. Eric and I will probably be too frazzled to pick you up ourselves, but we're glad to delegate a shuttle service.
We definitely encourage as many people to metro as possible. You'll go to the College Park/University of Maryland stop on the green line. We'll get you to the chapel, reception and back to the train when you're ready to go.
