Sadly I no longer have a navigator. I will be in DC this coming week and am thinking that from there I'll head to Prince Edward Island and am looking to figure out my route - not my favorite task. ...
Can't help you with your route, except maybe when you get further north you can get on Route 1. It's called the "Coastal Route" although not a lot of it's truly coastal. Just wanted to express my condolences that you lost your navigator.
