DC to Boston carpool needed this weekend

One of my team members for the MIT Mystery Hunt this weekend was planning to fly from DC to Boston tomorrow, but, ya know, snow. They've already told her her flight is cancelled. She trying to rebook to Thurs, but if it's not possible, she'll be looking for either advice on how to get to Boston in such weather, and/or a carpool.

Anyone doing DC to Boston for the Hunt, Arisia, or other purposes this weekend? If not, what would be your preferred method to travel up the East coast just after a blizzard?
