I know Mountain and the area like the back of my hand... 
My wife tells the story of her father who was driving in Northen Ontario in a blizzard. The kids asked him to slow down, and he replied that he knew the road like the back of his hand. The word "hand" was barely out of his mouth when he drove them into the ditch.

On unrelated note, your "Oh Shoot" cache is now beside a nice memorial the The Battle of Hill 70. It was just recently re-dedicated to the memory of the men who fought there. The minister of Defence even attended.
