I can't thank you enough for the input on the section around Glacier area.
I am still hoping for a warm winter and for some chance at Going to the Sun Road but if not I am happy to go via 18, 17 and 6 with the run around 49 for a little extra twists.
The tip about Waterton Lakes has me thinking we may stop short of Pincher Creek and stay the night in Waterton instead.
There looks to be some cool little 60's style motels.
Thanks also for the update on 40. I hope this stays clear for our ride through to Canmore.
