My husband and I are planning to drive our truck camper from Winnipeg on Highway 1 west into Saskatchewan. We will be leaving in two weeks and we know very little about the area. Is camping readily available along Hwy 1? Also, what are the odds of the weather getting "wintry" this time of year? We have the option of waiting until May to make the trip (final destination Jasper, Alberta) so would the weather possibly be better then? Any "must-see" sights along the way? Thanks for any help you can provide.
