Snowing at last. We checked out and left our bags while we went for a walk through Montréal's underground city. Most things were closed for the holiday which was disappointing. I felt sick and fainted which caused a stir with the security. We eventually picked up our bags and walked in the snow to the Greyhound terminal and bought tickets to Burlington. Compared to Amtrak, Greyhound terminals are a real scrum. Back across the border and through customs again. Took a taxi ride to our motel from the station and collapsed into bed, but couldn't sleep much.
