MaxSwell, I'm guessing you're riding that way stateside, huh? I'm just to the North in Manitoba.
Hummmm. I'm thinking. I've taken the trans-Canada hwy before on trips to Banff for camping. I recall vast prairie/grasslands/farm fields. Great for making time. Not so much for scenery. But then No. Dakota and E. Montana is no better. And Canada may be cooler. But I'm old and slow.
Still thinking.
Shoot me a PM and I can give you some better routes that will be scenic while traveling through Alberta - Highwood Pass, Jasper/Banff through Icefields Parkway, Crowsnest Pass, etc.
