we used the montreal metro to get around. i love trying out the different transportation systems in cities, especially when they speak french and you're like, ohhhh it's pronounced "san denee", not saint denis (st. denis blvd).
we had a great time checking out the neighborhoods, eating bagels (our favorite were st. viatur bagels), and walking around the curved cobblestoned streets of old town. oh, and of course the ivy covered old buildings on mcgill's campus. really stunning.
