The eastern half of Sask. and Manitoba offer the most consistant snows, blues and canadas. The last several years the western side of Sask. and Alberta have had little or no water.
Friends are telling me about taking there quad-runners through dry potholes looking for shed antlers and instead, are finding buffalo skulls from the 1800's. Now does that tell you how dry it is?
I've hunted in both places and 2 years ago it was sad. I'll need alot of snow and rain before I go back.
What the other guys have said is true, the Quills, the Pas, and other places are good. but, the pressure is bad (by Canadian standards). look for areas that have large lakes (in that corridor) with agriculturial land surrounding it.
