Highway 6 in AB Through Waterton Lakes and Hiway 17 in MT

We came back up to Canada on Hwy 17 and Hwy 6 about a month ago. Just watch out for livestock on the Hwy 17 as it travels through an open community range/ranch area and the cows roam freely. Almost had one hit the side of the truck three years ago as it bolted out of the ditch. Hwy 49 between St. Mary's and East Glacier is restricted to certain vehicle length. I think it is restricted to 24 feet or something like that. The road has quite a few twists and turns but the scenery is incredible.
