Alberta for sure, where big bucks die of old age. I prefer the Edmonton Bow Zone because there hasn't been any gun hunting at all since the mid 70s and these deer aren't pressured much at all. The Zone is about 1600sq miles of bowhunting bliss.
This was my "dream hunt" destination until I actually went there last year. I saved my pennies, and I'll be there again this Nov. I love this place!
