I followed Nina's advice and decided to stay in Jasper for tonight, thus making today a bit of a rest day. The hope (and forecast) is that tomorrows weather along the Icefield Parkway will be better than today. Spent the day relaxing around Jasper and the campground.
Whistlers Campground just south of Jasper, a very large establishment. The German guy I shared with last night told me it was the largest campground in North America. I have not been able to confirm or deny that fact; but it surely does accommodate a lot of people.
