October is a no-no.
The Whitehorse Motorcycle Club puts their bikes away by September 15.
Inuvik experiences 56 straight days of sunlight centered around June 21, when I was there. It got up to 95 degrees Farenheit the week before, and this is well north of the Arctic Circle.
I rode up in April and experienced snow with temperatures in the upper 20's and lower 30's. It was manageable on a Gold Wing because the authorities keep the far northern highways cleared and salted. I was cold, very cold, but the Canadian Rockies in the snow are breathtaking!
Think of a beautiful mountain valley laid out before you. The empty road snakes ahead and the fir trees and mountains are covered with fresh, pure white snow!
As the road rises out of the valley, my wet windshield freezes. As I drop into the warmer valley, the sheet of ice on my windshield breaks loose and flys right into my helmet!
