Ditch your car. We just got back from a East Coast tour, and Cabot Trail is one you do not want to miss. Ride your bike out there, it's really not that bad once you pass Montreal. It's even better if you cut through the U.S.
Have your rain gear ready.
Have to take a car, no bike this year. Not so easy just to "ditch" the car. I'm camping and taking a friend (who doesn't ride or even drive) and driving straight through. Plus I'm picking up my cousin in Moncton and taking him home to Ingonish for the 2 weeks. I know what the Cabot is, I've been there almost every other summer since I was born and driven it many, many times. My mom was born and grew up in Sydney, so I know the island quite well. My mom's cousin even owns 2 km of beach just north of Ingonish right on the Atlantic. Never anyone but me and my family there! My grandmother lives right on the trail just north of Ingonish, too.
