You can find some nice stretch of roads in Canada, but unfortuntaly when they are nice, well paved, well designed (banking or road texture) and well maintained ... they are full of enforcement and safety crew
On top of it; in Quebec ... they drive nothing better than some bad ass
motorcycles.
So we have to keep it under 120Km/h

The BMW Fascination I Driver Training course @ Mont Tremblant* (North of Montreal) in Quebec. The drive up there on public roads is very scenic.
P.S.: This use to be the old Formula 1 track for the Candian F1 Grand-Prix.
