For those of you uncomfortable driving in snowy/icey conditions:
I'm from the Boston area and I agree that people should avoid cabs if they can. Almost the entire drive to campus from the airport is on major highway so unless their is a blizzard, driving should not be that bad. The last road up to campus is a lot smaller and I have no idea how well it is salted/sanded but otherwise the roads are maintained well.
If you rent a car and are going to drive there a couple of tips to safe driving in winter conditions:
-Use your defroster if the window fogs up
-Drive slower than you normally would ESPECIALLLY on turns
-Give yourself extra time to brake, leave extra space between your car and the car in front of you
-Make sure when you rent a car that the car has anti-lock brakes and feel free to ask if it has 4 season tires on (grip better on ice)
-if you do feel yourself fishtail (when back end of car slips out of turn and front end still holds), gently press on brakes and steer yourself back on course
-and not that this will happen, but if on the slight chance you start going into a spin, stay calm, steer into the turn and and then steer out of the turn. Don't jerk the car the other direction, even though that feels instinctual.
But really, you'll be fine. Going slow is the key to handling ice. Cabs are way too much of a hassle (and expensive from Boston all the way to North Grafton) that if you are a confident, cautious driver you should just rent. Just my 2 cents.
